Abstract
Bi doped lanthanum manganites with the chemical composition of La0.67âxBixCa0.33MnO3 (x=0, 0.05, 0.1, 0.2) were prepared by the standard solid-state process. The Curie temperatures were measured to be 267 K for x=0, 248 K for x=0.05, 244 K for x=0.1 and 229 K for x=0.2 samples. It was found that the maximum value of the magnetic entropy change â£ÎSm⣠has reached the highest value of 6.08 J/kg K at 3 T for the composition with x=0.05. Nearly the same maximum entropy change was observed for the x=0 sample. A large decrease in the magnitude of the entropy change was observed for the x=0.2 sample.
