    Two new tools to map and measure the invisible properties of altermagnets

    The new big thing in magnetics is altermagnetism, a form of magnetism that promises to power the next-generation of electronics. Unlike ferromagnets, like a fridge magnet, where all internal atomic spins align to create a strong magnetic field, altermagnets have no net magnetic pull (strongly magnetic on the inside, but appears non-magnetic on the outside). This is similar to antiferromagnets where internal spins cancel each other out...

    Evgeny Tsymbal “holds” a rendering of the atomic structure found in ruthenium oxide, a material whose properties could point the way to faster digital devices packed with more memory.

    Most scientists would blanch at being labeled a spin doctor. But when it comes to Evgeny Tsymbal, Ding-Fu Shao and their colleagues, the lab coat fits.

    The University of Nebraska–Lincoln physicists have charged to the forefront of spintronics, a next-gen class of data storage and processing poised to complement the digital electronics that have ruled the realm of high tech for decades.

    Ahead of that future, though, loom nanoscale obstacles whose size belies their difficulty...
