“…Perovskite rare-earth chromites with the general formula RCrO 3 comprise an important class of multiferoic materials [1][2][3][4] that exhibit an astonishing variety of physical properties including electric, dielectric, magnetic, magneto-caloric, optic properties and so on. As a result, in the past several years, they have been fully investigated due to the promising potentials of applications such as insultor-metal transition [5], fuel cells (SOFC) [6], magnetocaloric materials [7], oxygen sensors [8], dielectrics [9], optic-magneto devices [10]..... Several factors like the ionic size of the R 3+ rare earth, the atomic valency of Cr-ions [11], Jahn Teller distortion [12] and the exchange between the d-orbitals of the B transition metal cation and the 2p-orbitals of oxygen anions [13][14] profoundly influence the electric, magnetic and other properties of these materials. Furthermore, these properties and the spin state of Cr ions can be controlled by a partial substitution either in R or/and Cr cation sites [13,15,16] which introduces a remarkable lattice distortion leading to various defects in the structure [17,18].…”
