The room temperature inflection of magnetism and anomalous thermoelectric power in lacunar compounds of La_0.85−xBi_xK_0.15MnO₃

Abstract

This study focuses on the effects of the substitution of a nonmagnetic ion on the structure, magnetism, and thermoelectric power of binary La0.85−xBixK0.15MnO3 (x = 0, 0.15, 0.3) manganites synthesized via a ceramic route.

Expansion of the multifunctionality in off-stoichiometric manganites using post-annealing and high pressure: physical and electrochemical studies

“…[1][2][3][4] All these have significantly increased interest in them and promoted the search for ways of their potential practical applications in magnetic memory devices, batteries, fuel cells, transistors, spintronic and electronic devices, magnetic refrigerators, medicine for treating cancer, and drug delivery. [5][6][7][8] The recent development of new magnetic refrigeration technology based on the MCE has become an alternative green and environmentally friendly approach compared to the conventional gas compression technique. 9,10 Among potential candidates for magnetic refrigeration, manganites show a low production cost, high chemical stability, and simple preparation.…”

Sizable magnetic entropy change in bismuth-substituted La0.75Bi0.1Na0.15MnO3 manganite

“…This is caused by strong hybridization among Bi-6s and O-2p orbitals, which seizes the 2p-electrons available for the DE for simultaneous hopping between Mn and O. [36][37][38] The variation of magnetic sensitivity with the temperature at low-field depends on both the structural and magnetic attributes of the specimen. Substitution of Bi at rare earth sites in most manganites tends to reduce dM/dT due to increased structural disorders.…”
