Critical Switching Characteristics of a Spin-Valve Structure in an Arbitrarily Directed Magnetic Field

The dependences of the spin-valve critical switching field with planar and perpendicular anisotropy of layers on the anisotropy coefficient and the magnetic-field direction are analytically and numerically obtained. It is established that the smallest critical values of the field and switching time are achieved when the magnetic field deviates from the anisotropy axis by an angle of 45°.
