Investigations are conducted for increasing chromium substitution, according to varying x values in the formula versus copper, for x=0, 0.2, 0.4, 0.6, 0.8, and 1. The magnetic response of polycrystalline samples under increasing external magnetic field from 0.4T to 5T is also studied. The partial crystal structure deformation/transition from delafossite CuFeO2 structure to corundum-type FeCrO3 structure containing CrO2 and Cr2O3 blocks is determined. The change in the crystal structure geometry with increasing Cr substitution is observed. Besides, prominent changes in magnetic ordering are observed from antiferromagnetic (x=1, 0.8, and 0.6) to ferromagnetic ordering (x=0.4 and 0.2) for high applied external magnetic fields above 2T.
