Paving the Way to Extremely Fast, Compact Computer Memory

July 17, 2024 • by Marc Airhart

Materials with high magnetoelectric coupling could be useful in novel devices such as magnetic computer memories, chemical sensors and quantum computers.

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 could be useful for a range of applications, including fast, compact computer memories. Image: Ella Maru Studio.
