What is it about?
The growth-induced magnetic anisotropy increases the magnetic damping in the LPE Bi-substituted YIG films, and increases with increasing Bi content. We have reported the rise in voltage observed in a spin thermoelectric generator incorporating Bi-substituted YIG films grown by liquid phase epitaxy, and explained the origin of the voltage rise based on the results of FMR measurements.

Why is it important?
Raising the thermoelectric voltage in spin thermoelectric generators is an important subject. We investigated the substitution of bismuth for yttrium to increase spin pumping at the paramagnetic metal and ferrimagnetic insulator (PM/FMI) interface, and tested bismuth-substituted iron garnet films grown by liquid phase epitaxy.
