SPIN PUMPING IN YIG/PT STRUCTURES UNDER CONDITIONS OF LOCAL NON-UNIFORM MAGNETIC FIELD

Using the inverse spin hall effect, a study of spin pumping by running magnetostatic surface waves in YIG/Pt microstructures was carried out, where an Fe application was used as a source of a local non-uniform magnetic field. The results of measuring the frequency dependences of the EMF are presented. It is shown, that the Fe application leads to an upward shift in frequency and «bluring» of the EMF peak near the lo-frequency boundary of the magnetostatic surface waves – its width increases, the amplitude decreases compared to the case of the YIG/Pt structure without the application.
