Abstract: The polycrystalline perovskitelike manganese oxides La_1-xA_xMnO$_{3+\delta }$ (A = Na, and K, $0.05c) and the bond distance of Mn-O. Results of magnetic measurements show that these materials can be utilized as suitable candidates for magnetic refrigerants with wide applied temperature span, for their significant entropy change and the easily tuned Curie temperature.
