  • Magnetization reversal
    Patent number: 9773603
    Abstract: A method of magnetization reversal, time stable ferrimagnetic material, a product and a domain comprising said material, a system for magnetization reversal, and information storage. Therein, a ferrimagnetic material is one in which magnetic moments of the atoms on different sublattices are opposed, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains.
    Type: Grant
    Filed: June 23, 2014
    Date of Patent: September 26, 2017
    Assignee: RADBOUD UNIVERSITEIT NIJMEGEN
    Inventors: Theodorus Henricus Maria Rasing, Johan Mentink, Andrei Kirilyuk, Alexey Kimel, Richard Francis Llewelyn Evans, Roy William Chantrell, Thomas Andrew Ostler, Joseph Barker
