Abstract

Herein, a systematic microscopic investigation of the crystal-field (CF) effects on Mn4+ ions doped at triclinic sites in the double perovskite La2ZnTiO6 crystal was performed using two independent modelling approaches based on CF theory: the exchange charge model and the superposition model.
