Fe3GeTe2
Product Description
Fe3GeTe2 is a two-dimensional van der Waals material known for its unique properties, including ferromagnetic behavior. Despite initial assumptions, it exhibits antiferromagnetic properties in its stoichiometric phase, with zero net moment. Through Fe defects and hole doping, it can achieve ferromagnetism. Researchers have demonstrated its potential in spintronics, utilizing voltage to control electron spin information, enabling ultra-low power data storage and retrieval. With a hexagonal crystal structure and a crystal size of approximately 2-3 mm, Fe3GeTe2 holds promise for spintronic devices operating at low power consumption.
