Özet
The effects of Cr doping on structural, magnetic and magnetocaloric properties of La0.94Bi0.06Mn1-xCrxO3 (x = 0, 0.05, 0.1, 0.15, 0.2, 0.25) samples were investigated. It has been observed in X-ray analyses that the substitution of Mn by Cr produced no remarkable structural change and only the diffraction peaks for orthorhombic symmetry were obtained for all samples. The decrease in the Curie temperature and saturation magnetization with Cr content could be due to weakening of the ferromagnetism in Cr doped samples. The decrease in magnetic entropy change was attributed to the decrease in saturation magnetization with increasing Cr content.
