Abstract

See full text

A magnetic device is described. The magnetic device includes a magnetic junction, a spin-orbit interaction (SO) line and a dipole-coupled layer. The magnetic junction includes a free layer. The SO line is adjacent to the free layer, carries a current in-plane and exerts a SO torque on the free layer due to the current passing through the SO line. The free layer being switchable between stable magnetic states using the SO torque. The SO line is between the free layer and the dipole-coupled layer. The dipole-coupled layer is magnetically coupled to the free layer. At least one of the free layer and the dipole-coupled layer has a damping of greater than 0.02.
