Abstract

We report for the first time the synthesis of [C(NH2)3]Cr(HCOO)3 stabilizing Cr2+ in a formate perovskite, which adopts a polar structure and orders magnetically below 8 K. We discuss in detail the magnetic properties and their coupling to the crystal structure based on first principles alculations, symmetry, and model Hamiltonian analysis. We establish a general model for the orbital magnetic moment of the [C(NH2)3]M(HCOO)3 (M = Cr, Cu) based on the perturbation theory, revealing the key role of the Jahn-Teller distortions. We also analyzed their spin and orbital textures in k-space, which show unique characteristics.
