MAGNETIC DEVICE HAVING PERPENDICULAR MAGNETIZATION AND INTERACTION COMPENSATING INTERLAYER

摘要

This magnetic device comprises a least two layers made of a magnetic material that are separated by at least one interlayer made of a non-magnetic material. Said layers made of a magnetic material each have magnetization oriented substantially perpendicular to the plane of said layers. Said layer of non-magnetic material is capable of inducing an antiferromagnetic coupling field between said layers made of a magnetic material, the direction and amplitude of this field making it possible to attenuate the effects of the ferromagnetic coupling field of magnetostatic origin that occurs between said magnetic layers.
