Magnetocaloric properties of doped lanthanum manganite films

Abstract: LaMnO3 films doped with Ca, Ba, or Sr have been fabricated using the metalorganic decomposition technique. These films exhibit paramagnetic-to-ferromagnetic phase transitions at 250, 300, and 350 K, respectively. By measuring the film magnetization as a function of field and temperature we have determined the entropy change associated with these transitions. The large magnetization of these materials results in a total entropy change a factor of five less than that of gadolinium, the prototypical high-temperat… Show more

“…Recently, scientists have started doing research on the MCE properties of thin films, but only a few reports are currently available, [28][29][30][31][32][33] although in principle, such films will be easier to integrate into electronic structures for applications. 17 However, with the currently available magnetic materials, this high efficiency is only realized in high magnetic fields.…”

“…The MCE have been investigated in a very wide spectrum of materials that include elemental metals, [48] Laves phases, [49] manganites, [50] silicides, [51] lanthanides, and Huesler [52] alloys in the form of bulk [53] and thin films. [54] To explore new scenario from the traditional MCE systems, the mesocrystal-embedded oxide system offers a new media to trigger these green energy applications. In the path of realizing high value of the MCE, the significant improvement of interfacial effects and strain engineering can be intuitively thought by an increase of the surface to volume ratio, which can be easily achieved by material combinations in the form of mesocrystal-embedded systems.…”

“…As other advantages, they present the possibility to tune their magnetic transition temperature by the substitution on both R-sites and Mn-sites. The MCE of La 1-x A x MnO 3 (A = Ca, Sr, Ba) manganites was first studied by Moreli et al [13]. A large MCE in La 1-x A x MnO 3 polycrystalline samples (0.2 B x B 0.…”

“…However, the use of the Gd is limited due to its expensive cost price. Nevertheless, some other candidates have been found to exhibit large MCE, such as Gd 5 (Si x Ge 1-x ) 4 [9], La (Fe 1-x Si x ) 13 [10], MnFeP 1-x As x [11], and Tb 1-x Gd x A l2 [12].…”
