Scientists Discover a New Kind of Magnet (ieee.org)
Wave723 shares a report from IEEE Spectrum: A new kind of magnet, theorized for decades, may now have been experimentally proven to exist. And it could eventually lead to better data storage devices. In a normal magnet, the magnetic moments of individual grains align with each other to generate a magnetic field. In contrast, in the new "singlet-based" magnet, magnetic moments are temporary in nature, popping in and out of existence. Although a singlet-based magnet's field is unstable, the fact that such magnets can more easily transition between magnetic and non-magnetic states can make them well-suited for data storage application. Specifically, they could operate more quickly and with less power than conventional devices, says Andrew Wray, a materials physicist at New York University who led the research. Now, Wray and his colleagues have discovered the first example of a singlet-based magnet that is robust -- one made from uranium antimonide (USb2). "It ends up taking very little energy to create spin excitons for uranium antimonide," Wray says. "This is essential for the singlet-based magnet, because if it took a lot of energy, then there wouldn't be enough spin excitons to condense, stabilize one another, and give you a magnet." The research has been published in the journal Nature Communications.
How do they work?
TL;DR - Not a monopole (Sadly)
How does it work?
So....does this advancements in elector motors?! Other than storage, what other practical application would this serve?
Life is not for the lazy.
Insane Clown Posse is really going to be confused now.
The Limitations of USb2 will be its 480mb/s transfer rate. And how I keep plugging it in the wrong way. USB-C is way better solution in both regards. :X
You've got an extremely unstable new magnet type with low voltage thresholds and quick cycling, so naturally not only do you want to try to store data with it, you want to make it out of Uranium Antimonide with the denotation "USB2"
Let's kick that back to the marketing team there, boss.
How can this lead to better storage devices? The only thing I can think of is another way to coat platters in a spinning physical HD. The last time I checked spinning HD where on the way out.
I read at +2. If your post doesn't reach that level I will not see or respond to it.
So our hard drives will be coated with uranium antimonide? That sounds like fun.
Sweet, radioactive storage!
For this reason, God sends them a powerful delusion(operation of wandering)(planet) so that they will believe the lie.

It has blood on it!
ABCNews: Eclipse makes pendulum wander
We have finally found a place to dump all the nuclear waste! It's going to our next gen data centers!
I see a glowing future ahead of us.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
I can't wait for USB sticks to come in 12" thick lead-lined concrete cases with free shipping from Alibaba.
Let's see the delivery guy try throwing that package across the front yard.
Uranium (and similar) for the win.
What could possibly go wrong? Heh
High temperature singlet-based magnetism from Hund’s rule correlations
Not paywalled. Thank you very much, Nature.
When all you have is a hammer, every problem starts to look like a thumb.
"The concept for singlet-based magnets dates back to the 1960s. The temporary nature of their magnetic moments arises from a "spin exciton," which can occur when electrons collide with one another under the right circumstances. Excitons are quasiparticles made up of electrons bound to their positively-charged counterparts, known as holes. In normal excitons, the magnetic moments of the electrons and holes usually point in opposite directions and cancel each other out. In contrast, for spin excitons, the magnetic moments of the electrons and holes align the same way."
Electron+Holes quasi particle? Yet you have a magnetic field in a vacuum, and in light....
Maybe don't go speaking to a scientist.....
It's just F/2 electric resonance.
I think it's not possible (even in resonance model).
I have an oscillation across the photon in resonance model. You kick the photon with two oscillations, it travels in direction that keeps it closest to resonance, the residual of velocity shows up as an oscillation across velocity.
I think this was velocity:

Electron is a stack of F2 donut, -ve monopole, F2 anti-donut. Donuts are multiples of the resonant wavelength, they are the same as a photon. An F2 is two wavelength. It's oriented by the resonance field, and spins half turn per 1F oscillation of the field, i.e. F2 is two wavelengths of resonance hence half the twist per 1F.
In the process it unpacks the magnetic field in the photon in the donut to F/2 electric resonance.
Magnetic is F/2 electric, it literally is the same thing as electric. A half harmonic, it doesn't interact much, just a sub proton jiggle with electric unless you add spin or velocity to take it away from F/2.
And the direction of field is the direction of spin, look at the electron from the top.... clockwise = north, look at it from bottom, anti-clockwise = south.... since you can always view the spin from two poles, there must always be two poles...
Think about the photon, if the magnetic oscillation was closer to F than the velocity oscillation, then the magnetic would BECOME the velocity and the velocity oscillation would become the magnetic and the photon would head off at right angles! That's how interwined electric and magnetic are.... and there is a case where this right angle thing happens*
This link below helps to understand that EM Wavelength is the *difference* between the F oscillation in light and the F oscillation it's hitting or being emitted from, rather than some inherent property of light. So as not to confuse EM frequency and F.

* And the case where magnetic oscillation becomes electric oscillation at right angles? Where does that happen?
Postulate N1 Black holes, black hole is a 2F universe relative to the outer universe 1F. Magnetic inside the blackhole is the electric component outside (i.e. 2F/2 = 1F!) i.e. there is a right angle turn happening at the event horizon. The spin of the blackhole (i.e. velocity tangential to the blackhole) appears as velocity redial towards and away from the center of the blackhole universe on the inside.... i.e. velocity switches to right angles across the event horizon as 1F outside becomes 2F inside.
About that big bang theory you have there.... if we're in a black hole, the event horizon is the edge of the observable universe, and the accelerating velocity outwards is from the spin of the blackhole we are in.
If the magnetism goes away quickly, the material wouldn't be suitable for mass storage such as a harddisk of magnetic tape. However, then it could be suitable as a core of a coil, the same as a coil with a ferrite core.
Is this material diamagnetic, paramagnetic of ferromagnetic?
Someone not reading this post;)
...the Human Tripole.
I suspect the hard drives based on this would be 10x faster if they used USb3 instead of USb2.
