Angular-dependent ferromagnetic resonance of exfoliated yttrium iron garnet film under stress
Abstract
Yttrium iron garnet (Y3Fe5O12, YIG) plays a significant role in the field of spintronics due to its low magnetic damping and insulating characteristics. However, most studies have focused on YIG in bulk form or as film grown on rigid substrates. In this study, YIG film has been exfoliated from two-layer-graphene-covered (111) Gd3Ga5O12 (GGG) substrate. The magnetic properties of the YIG film under stress are investigated in detail via angular-dependent ferromagnetic resonance. The relationship between magnetic parameters and compressive/tensile stress has been established. The findings of this work are expected to advance the applications of flexible YIG films.
