Double perovskites for room temperature magnetocaloric tasks.

Number: pap. 0033

Summary

In previous studies, we have reported that double perovskite La2NiMnO6 (LNMO) presents a nonnegligible potential for room temperature magnetocaloric tasks. With the aim of improving even further the cooling performance and the working temperature range of double perovskites, we report preliminary results on the magnetic and magnetocaloric properties of La2MnFeO6 and related compounds. The substitution onto the lanthanum site enables us to cover a wide operating temperature range extending beyond 300 K. For some optimal growth conditions, the entropy change varies slowly over an unusually large temperature range, which is of clear interest from a practical point of view.
