ON THE ANISOTROPY OF EXCHANGE IN YTTERBIUM IRON GARNET.
Abstract
The exchange splittings of the lowest 2F5/2 and 2F7/2 doublets of Yb(3+) in YbIG are evaluated in terms of the exchange potential parameters as given in a previous article. The wave functions of White, and Hutchings and Wolf were used. A good four parameter fit of the experimental exchange splittings is obtained by adopting essentially zero values for the rare-earth-iron exchange interactions that take place through the nearest neighbor oxygen ions. The chief result of this analysis is that the rare-earth-iron exchange interaction takes place primarily through the next-nearest neighbor oxygens (2.43A); the nearest neighbor oxygens (2.37A) are comparatively inert.
