论文摘要
考虑了COFE2O4单晶的红外光学,磁光和磁迹性。在Voight实验几何形状中研究了磁引动的COFE2O4尖晶石中自然光的磁传输和磁反射。这些磁光效应非常高,并且与磁场下的基本吸收边缘和杂质吸收带的变化相关。它表现出这些效果在很大程度上取决于磁场相对于晶体的晶体学轴的大小和方向。建立了红外光谱范围内的光的磁磁吸附与COFE2O4尖晶石的磁截图之间的明显联系。磁截图对COFE2O4晶体的磁各向异性常数的贡献表明异常出色。
The infrared optical, magneto-optical and magnetostrictive properties of CoFe2O4 single crystal are considered. The magneto-transmission and magneto-reflection of natural light in magnetostrictive CoFe2O4 spinel are studied in the Voight experimental geometry. These magneto-optical effects are very high and associate with a change of the fundamental absorption edge and impurity absorption bands under magnetic field. It is presented the effects strongly depend on both the magnitude and orientation of magnetic field relative to the crystallographic axes of the crystal. The clear connection between magneto-absorption of light in the infrared spectral range and magnetostriction of CoFe2O4 spinel is established. The contribution of magnetostriction to the magnetic anisotropy constant of the CoFe2O4 crystal is shown to be abnormally great.
