Structural, magnetic and magnetotransport properties of La0.67Ba0.332−xRbxMnO3 perovskites prepared by flux method

Magnetocaloric effect and critical behavior near the first to second-order phase transition of La0.7Ca0.3−xSnxMnO3 compounds

“…Recent studies have shown that there are some ways to modify the order of phase transition in La 0.7 Ca 0.3 MnO 3 compound, including reduced dimensionality [11], reduced crystalline or particle size [9,13], and doped suitable elements into the La/Ca [14][15][16][17][18] and/or Mn sites [19,20]. Depending on crystalline size, dopant types, and doping content, modifying the FOPT to SOPT results would be different.…”

The investigation of structural and vibrational properties and optical behavior of Ti-doped La0.67Ba0.25Ca0.08Mn(1−x)TixO3 (x = 0.00, 0.05 and 0.10) manganites

“…[5][6][7][8][9][10] Recently, the exceptional properties of bariumdoped lanthanum manganites (La 1Àx Ba x MnO 3 , LBM) have secured a prominent position in many industrial technologies, such as magnetic sensors. [11][12][13][14] These manganites demonstrate a transition from metal behavior to insulator behavior, followed by a ferro-paramagnetic transition, i.e., the Curie temperature (T C ), which is characterized by high magnetic entropy. 15,16 The substitution of bivalent cations for the rare-earth cations in manganites leads to converting twice as many Mn 3+ into Mn 4+ ions to donate information to the double exchange interactions, which are the origin of the ferromagnetic behavior.…”
