采用反应离子束溅射技术，采用气相直接外延生长方法合成了非热力学石榴石Bi3Fe5O12。在a=12.495 A的衬底上生长的薄膜的室温饱和磁化强度为1500G。单轴各向异性能为+7.2×104erg/cm~3。转换电子穆斯堡尔谱测量表明，近晶格匹配薄膜中24d位和16a位的内场分别为420和490 kOe。24d点的内场比YIG的大30kOe。内场方向与薄膜法线的夹角为34.8°。采用反应离子束溅射技术，通过气相直接外延生长制备了非热力学石榴石Bi3Fe5O12。在a=12.495 A的衬底上生长的薄膜的室温饱和磁化强度为1500G。单轴各向异性能为+7.2×104erg/cm~3。转换电子穆斯堡尔谱测量表明，近晶格匹配薄膜中24d位和16a位的内场分别为420和490 kOe。24d点的内场比YIG的大30kOe。内场方向与薄膜法线的夹角为34.8°。
Nonthermodynamical garnet Bi3Fe5O12 was synthesized by direct epitaxial growth via vapor phase using a reactive ion beam sputtering technique. The lattice constant was 12.631 A. The saturation magnetization of the film grown onto a substrate (a=12.495 A) was 1500 G at room temperature. The uniaxial anisotropy energy was +7.2×104 erg/cm3. The conversion electron Mossbauer spectroscopy measurement indicates that the internal fields of 24d and 16a sites in the nearly lattice‐matched film were 420 and 490 kOe, respectively. The internal field of the 24d site was larger by 30 kOe than that in YIG. The angle between the direction of the internal field and the film normal was 34.8°.Nonthermodynamical garnet Bi3Fe5O12 was synthesized by direct epitaxial growth via vapor phase using a reactive ion beam sputtering technique.
