Colossal Magneto Resistive (CMR) materials with the compositional formula, La0.34R0.33Ba0.33MnO3 (R=Pr, Nd, Sm and Gd) were prepared by the sol gel technique. After characterizing the samples structurally, a systematic investigation of magnetization has been undertaken, over a temperature range 70–300K at 0.05T magnetic field. An effort has been made to calculate the magnetocaloric behavior of all...
