Influence of spin-orbit interactions on the cubic crystal-field states of the d4 system*

摘要

It has been shown that for the highly-correlated d4 electronic system thespin-orbit interactions produce, even in case of the cubic crystal-fieldinteractions, a singlet ground state. Its magnetic moment grows rapidly withthe applied magnetic field approaching 4 uB for the Eg state, but only 3 uB forthe T2g state. The applicability of the present results to the Mn3+ ion inLaMnO3 is discussed. Keywords: crystal-field, spin-orbit, orbital moment. PACS: 71.70.E, 75.10.D
