文摘

Taking into account the spin–spin (SS), spin-other-orbit (SOO), the orbit–orbit (OO) magnetic interactions besides spin–orbit (SO) interaction, the zero-field splitting (ZFS) of ²E state and g factors of (²E) term for Cr³⁺ ions in Al₂O₃ crystal are studied in the intermediate-field coupling scheme using complete diagonalization method. It is shown that the ZFS of ²E state and g factors of (²E) term arise from five microscopic mechanisms including SO coupling mechanism, SS coupling mechanism, SOO coupling mechanism, OO coupling mechanism, and SO–SS–SOO–OO combined coupling mechanism. The relative importance of the five contributions to the ZFS of ²E state and g factors of (²E) term is investigated.
