The field of ultrafast magnetism explores how flashes of light can manipulate a material's magnetization in trillionths of a second. In the process called all-optical switching (AOS), a single laser ...

Scientists have discovered that electron spin loss, long considered waste, can instead drive magnetization switching in spintronic devices, boosting efficiency by up to three times. The scalable, ...

Fig.1: Schematic illustration of the experimental approach. The magnetic heterostructure is first excited by a femtosecond infrared laser pulse (2.1µm wavelength), initiating the process of ...

A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance shows up almost everywhere scientists look—even in systems where the ...

Scientists transform wasted spin loss into usable energy, powering a new principle for magnetic control and next-gen ultra-low power devices. Spintronics is a technology that utilizes the "spin" ...
