| Abstract: | The magnetic entropy change of magnetic perovskite type compounds has recently been found to be larger than that of gadolinium.The Curie temperature can be adjusted easily over a wide temperature range by substitution of iron.These compounds may thus be useful as magnetic refrigerants even at room temperature. |
