"Unveiling these effects at the scale of atomically thin nickel iodide flakes was a formidable challenge," said Frank Gao, a postdoctoral fellow in physics at UT and co-lead author of the paper ...

When researchers irradiate a thin layer of nickel iodide with an ultrafast laser pulse, corkscrew-shaped features called “chiral helical magnetoelectric oscillations” arise. These features ...
