Pȩkała, M and Pȩkała, K and Drozd, V and Fagnard, JF and Vanderbemden, P (2010) Magnetocaloric effect in La0.75Sr0.25MnO3 manganite. Journal of Magnetism and Magnetic Materials, 322. pp. 3460-3463. ISSN 0304-8853Full text not available from this repository.
The polycrystalline manganite La0.75Sr0.25MnO 3 prepared by an alternative carbonate precipitation route reveals the rhombohedral perovskite structure. Magnetization isotherms measured up to 2 T are used to determine Curie temperature of 332 K by means of Arrott plot. Maximum of magnetic entropy change is found at Curie temperature. The relative cooling power equal to 64 J/kg for 1.5 T magnetic field, is superior as compared to the manganite with the same chemical composition from the solgel method. © 2010 Elsevier B.V.
