Prognostic CMR predictors of adverse outcomes in patients with suspected ARVC

Magnetic and magnetocaloric properties of La0.55Bi0.05Sr0.4CoO3 and their implementation in critical behaviour study and spontaneous magnetization estimation

“…48 The magnitude of DS m increases with an increasing strength of m 0 H. The maximum value of DS decreases from 2.66 J kg À1 K À1 for the La 0.6 Sr 0.4 CoO 3 sample prepared by the solid-solid reaction 49 (2.10 J kg À1 K À1 for La 0.6 Sr 0.4 CoO 3 made by the sol-gel method 14 ) to 1.45 J kg À1 K À1 under an applied magnetic eld of 5 T. This indicates that Bi substitution leads to a marginal decrease in the MCE properties with a reduced transition temperature. On the other hand, the obtained value of Bi-doped cobaltite is comparable to those obtained in other cobaltites, 3,14,50,51 indicating that our sample could be used as a refrigerant material in magnetic cooling devices.…”

“…As a member of perovskite oxides, cobaltites are important agile and multifunctional materials that are very promising for several applications, including high-temperature oxygen separation membranes, cathodes in solid oxide fuel cells (SOFCs), magnetic storage, and magnetic refrigeration. [1][2][3] The Co-based sister compounds of manganites have been less intensively studied. [4][5][6] It is well-known that the similar Hund's rule exchange energy and crystal-eld energy both lead to an additional spin-state degree of freedom in cobaltites, which results in close competition between the multiple ground states.…”
