摘要: The absorption magnetic circular dichroism in EuTe was investigated as a function of the field at T = 2?K. In order to describe optical spectra theoretically, we developed model that takes into account lattice field. allows us calculate spectrum continuous intensity. theory accounts for strongly dichroic seen high fields, and its evolution towards B 0 spectrum, which is described by much weaker broader line. drastic changes observed experimental are fully explained dependence Eu2+ spin arrangement on external
