OSCILLATOR AND METHOD OF OPERATING THE SAME

摘要

PURPOSE: An oscillator and an operating method thereof are provided to generate high frequency signals without application of external magnetism using phenomenon of a spin transfer torque. CONSTITUTION: The magnetic moment of a magnetic layer(FP1) applies current on an oscillator for precession. The current is applied from the magnetic layer to an anti- ferroelectric material layer(AF1). Electronics are applied from the anti- ferroelectric material layer through a pinned layer(FF1) to a free layer. The electronics passing through the pinned layer and flowing to the magnetic layer has the same spin direction as the pinned layer. The electronics can apply the spin torque on the magnetic layer. The magnetic moment of the magnetic layer can be perturbed by the spin torque.
