A Brief Review on Magnetic and Magnetocaloric Properties of La-Type Manganites

Abstract

In present chapter, experimental techniques and preparation conditions adopted for the synthesis of La-type manganites and their influence on the structural, magnetic and magnetocaloric properties are briefly reviewed. The effects of various strategies of substitutions on magnetic and magnetocaloric properties are addressed. Further, our synthesis and findings on Mn-Fe substituted manganites are presented. It was found that partial substitution of Mn by Fe results in decreasing the magnetization and the Curie temperature, but the magnetic entropy change values remained in the range suitable for magnetic refrigeration.
