Abstract
It is shown that the Co3+ ion can have a non-magnetic ground state as the realization of the Jahn–Teller effect. This non-magnetic localized singlet ground state with a highly magnetic excited doublet is formed by the trigonal distortion of the local octahedral surrounding. Such structure is exactly accounted for by crystal-field interactions if the intra-atomic spin–orbit coupling is correctly taken into account. The presented crystal-field-based approach can be applied to other Co3+ and Fe2+ ion compounds.
