Time Aspects of the 180° Pulsed Magnetization Reversal of Ferrite–Garnet Films with Complex Anisotropy

It is shown that a material having four stable positions of the orientation of the magnetization vector makes it possible to double the density of magnetic recording (for example, in MRAM devices) without substantial modifications of production process. This finding is based on investigations of the time aspects of the 180° pulse magnetization reversal of ferrite–garnet films with planar anisotropy, in the region of external fields where the mechanism of uniform rotation of magnetization operates.
