Light-induced Thermomagnetic Recording of Ferromagnetic Thin-film on Silicon Waveguide for Solid-State Magneto-Optical Memory

We firstly demonstrate light-induced thermomagnetic recording of a ferromagnetic thin-film CoFeB placed on a silicon waveguide. The magnetization reversal is observed when light propagates in the waveguide and evanescently heats up the thin-film magnet.

Automated summary

We demonstrate the light-induced thermomagnetic recording of a ferromagnetic thin-film CoFeB placed on a silicon waveguide for the first time, where magnetization reversal is observed when light propagates in the waveguide and heats up the thin-film magnet.
