Title:
SPIN HALL OSCILLATOR, MAGNETIC RECORDING DEVICE, AND CALCULATOR
Document Type and Number:
WIPO Patent Application WO/2020/179493
Kind Code:
A1
Abstract:
This oscillator 100A comprises a spin current source 110 and a free layer 111 that is joined to the spin current source 100. The free layer 111 has a magnetization-hard axis parallel to a quantization axis of a spin current injected by the spin hall effect of the spin current source 110.
