Magnetic arrangement is based on spin polarization and rotating magnetization, memory and writing

摘要

Magnetic spin polarising and magnetisation rotation device with memory and writing process, using such a device. According to the invention, the device includes a means of polarising the spin of electrons, which consists of a magnetic layer (20) whose magnetisation is perpendicular to the plane of magnetisation of the respective anchored (12) and free (16) layers. The magnetisation in the free layer (16) then rotates within a plane, which is either the plane of the layer, or a perpendicular plane. Application in the manufacture of magnetic memories.
