Magnetization reversal phenomena and bipolar switching in La1.9Bi0.1FeCrO6

A magnetization reversal phenomenon in double perovskite La1.9Bi0.1FeCrO6 has been investigated. Polycrystalline sample was prepared by conventional solid state reaction method and it was found to stabilize in orthorhombic crystal structure with Pnma space group. Temperature dependent magnetization study at low fields has shown the spontaneous magnetization reversal phenomena below the compensation temperature (Tcomp~186 K) and it is attributed to the antiferromagnetic arrangement of uncompensated weak ferromagnetic clusters of Fe and Cr. The field dependent tunable bipolar magnetic switching and observation of normal and inverse magnetocaloric effects evidence the magnetization reversal phenomena in La1.9Bi0.1FeCrO6.
