“…The interest of such material is that, if Fe and Cr sublattices are chemically ordered, the expected antiferromagnetic super-exchange coupling 17 between Fe and Cr 18 may yield a ferrimagnetic ordering with a net predicted magnetic moment of 2 µ B per unit cell. 19 However, the measured values of magnetization are widely spread, [20][21][22][23][24][25][26][27] from nearly zero with antiferromagneticlike behavior 20,26 to large magnetic moments and magnetic saturation at 0.5 T. 21,22 In the first case, the absence of a strong ferrimagnetic signal has been attributed to the lack of chemical order in the double-perovskite, with Fe and Cr atoms being randomly distributed. 26 All the reported hysteresis loops of BFCO thin films have been measured by integrating methods, like vibrating sample magnetometers, 22,23 SQUID, 21,25,26 or alternating gradient magnetometer.…”
