Low temperature magnetic and magnetocaloric studies in YCr0.85Mn0.15O3 ceramic


We have investigated low temperature magnetic and magnetocaloric properties of manganese (Mn) doped YCr0.85Mn0.15O3 (YCMO) polycrystalline compound, synthesized via solid state reaction route. The lattice volume was found to increase in comparison to that of pristine YCrO3 (YCO) compound. On the other hand, the paramagnetic-antiferromagnetic Neel temperature (T-N similar to 132 K) was found to be lower than that for YCO ceramic. On cooling below T-N, under field cooled (FC) mode with an applied magnetic field of 0.02 T, magnetization flipped the polarity from positive to negative at T-comp = 62 K. Furthermore, the magnetization switching temperature, defined as compensation temperature, exhibited field dependency and decreased with increasing field. Besides, the magnetization reversal phenomenon disappeared under higher applied magnetic field values. For the first time, the magnetocaloric effect for this compound was measured near 36 K through the parameters like magnetic entropy change (-Delta S) = similar to 0.186 J kg(-1) K-1 and the relative cooling power (RCP) similar to 6.65 J kg(-1), under an applied field of 5 T.
