摘要
A coherent nonlinear coupling between the charge and spin dynamics of electrons results in the rectification of microwaves,which is enhanced through resonant magnetization dynamics such as ferromagnetic resonance.This property,known as the spin rectification effect,enables the spin dynamics within a material to be electrically detected with a high sensitivity.Techniques utilizing this property have been widely used to study the magnetization dynamics of various ferromagnetic materials and structures in the past decade.Additionally,the coherent nature of spin rectification opens the door for spintronic devices to be used in phase-resolved microwave sensing techniques.In this work we review the physics of spin rectification and its applications in several interesting topics of magnetism and spintronics.
