Enhanced magnetocaloric properties with a tunable Curie temperature in (1 − x)La0.55 □ 0.1Ca0.35MnO3/xLa0.7Ca0.2Sr0.1MnO3 system (0 ≤ x ≤ 1)

The magnetocaloric effect properties for potential applications of magnetic refrigerator technology: a review

“…PM has several advantages, including cost-effectiveness, shorter production processes, relative ease of production, chemical stability, good structure, environmental friendliness, resistance to corrosive environments, SOMT behavior, excellent MCE properties, and easily adjustable T C within the room-temperature range. 40,42,43,114–124…”

“…To date, innovative types of materials include Heusler alloys, 28,29 LaFe 13Àx Si x alloys, [30][31][32][33] Fe-based alloys, 34 MnAs, 35 spinnel ferrites, [36][37][38] perovskite magnanites, 9,[15][16][17]27,[39][40][41] double perovskites, 19 and composite. [42][43][44] This was aimed at obtaining MCE materials with ideal criteria for magnetic refrigeration applications. Based on the criteria proposed by Phan et al, perovskite manganites have the potential as a permanent magnetic refrigeration applications.…”
