| Abstract: | The single-ion anisotropy model together with the superposition model of the zero field splitting are used to analyse the growth-induced anisotropy of YIG films containing Bi3+ ions. Three different mechanisms are discussed. It is shown that the most probable source of anisotropy is the modification of the electron structure of Fe3+ ions by interactions in Fe3+O2;Bi3+ triads. |
