【 摘 要 】

Rare-earth iron garnet thin films with perpendicular magnetic anisotropy (PMA) have recently attracted a great deal of attention for spintronic applications. In this study, magnetic anisotropy of epitaxial garnet films was analyzed theoretically, and (YBiLuCa)(3)(FeGe)(5)O-12 mono-crystalline films with PMA have been successfully grown with liquid phase epitaxial (LPE) method on Gd3Ga5O12 (GGG) substrates. Microstructural properties, chemical composition and magnetic properties of the epitaxial films were discussed in detail. We found that growth temperatures played a significant role in the uniaxial anisotropy of the epitaxial (YBiLuCa)(3)(FeGe)(5)O-12 mono-crystalline films. Ferromagnetic resonance linewidth of (YBiLuCa)(3)(FeGe)(5)O-12 films with thickness of 170 nm was 8.06 Oe@12 GHz, which indicated that the epitaxial (YBiLuCa)(3)(FeGe)(5)O-12 mono-crystalline films had a great potential application in spintronic devices.
