Magnetically Compensated Nanometer‐Thin Ga‐Substituted Yttrium Iron Garnet (Ga:YIG) Films with Robust Perpendicular Magnetic Anisotropy

Advanced Electronic Materials, EarlyView.
This study reports on the remanent magnetization 4πMr and the temperature dependence of the net magnetization of magnetically compensated Ga:YIG films. For samples with very low net magnetic moments, the compensation points Tcomp and the Curie temperatures TC are determined. Ga:YIG films exhibit a significant increase in effective magnetization 4πMeff,
