A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

Large data centers rely on magnetic materials as data storage media, in which bits of information (i.e., "0" or "1") are encoded by the magnetization direction (i.e., "up" or "down"). The term "magnet ...

A laser trick in nanometer-thin magnets hints at faster storage and computing without exotic laboratory conditions ...

All ferromagnetic materials have atomic magnetic moments that are aligned parallel to each other within small regions called domains. Within these domains, the spontaneous magnetization present is ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the ...

Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic ...
