Researchers from the Hebrew University of Jerusalem in Israel have made a recent discovery that could change the face of spintronics research - the most important equation used to describe magnetization dynamics, namely the Landau-Lifshitz-Gilbert (LLG) equation, also applies to the optical domain.
A spintronics device developed by Professor Capua's lab
The new discovery has relevant applications in optical magnetic recording, namely in optically-controlled MRAM technology. Manipulation of the magnetization order parameter on optical timescales is key for ultrafast spintronics, which allows for faster, energy-efficient optically-controlled MRAM technology.
Assistant Prof. Amir Capua heads the Spintronics Lab at the Institute of Applied Physics and Electrical Engineering at the Hebrew University of Jerusalem. Prof. Capua has an impressive background in both industry (IBM, Intel) and academia, with experience in the fields of semiconductor laser physics, quantum optics, spintronics and more. Now he heads a team that explores spin transport phenomena in atomically engineered solid state devices for novel sensing, processing, and memory applications.
