Electrical, thermal and magnetic properties of Bi doped La 0.7− x Bi x Sr 0.3 MnO 3 manganites

Effect of Particle Size on Magnetic Phase Coexistence in Nanocrystalline La0.4Bi0.3Sr0.3MnO3

“…Values of T C , θ p , eff , M 90 kOe , H C , M 0 , M sat , critical fields (H CR ), and other calculated microstructural parameters for LB3SMO-Bi 0.3 Sr 0.3 MnO 3 , represents an intermediate system, as if it were a mixture of both the parent phases, showing signatures of magnetic phase coexistence. Similar characteristic of magnetic phase coexistence across intermediate concentration of Bi 3+ has been previously observed in case of La 0.67−x Bi x Sr 0.33 MnO 3 , La 0.7−x Bi x Ca 0.3 MnO 3 , Pr 0.6−x Bi x Sr 0.4 MnO 3 etc [29][30][31][32][33][34]…”

“…Recent literatures on Bi 3+ substituted perovskite system (i.e., LaSrMnO 3 [29,30], LaCaMnO 3 [31,32], PrSrMnO 3 [33,34], LaBaMnO 3 [35], and LaAgMnO 3 [36,37]) reveal an overall reduction T C and net magnetization for partial Bi 3+ content. However, as Bi 3+ concentration increases, a change in magnetic ground state has been noticed for LaSrMnO 3 [29,38], LaCaMnO 3 [31,32], and PrSrMnO 3 [34].…”

Magnetic properties and magnetocaloric effect in La0.7Sr0.3−xBixMnO3 manganites

“…There are few reports on magnetic properties for Bi-doped strontium manganites, namely, La 0.7-x Bi x Sr 0.3 MnO 3 [8,9] and Pr 0.6-x Bi x Sr 0.4 MnO 3 [10]. In these manganites, the Bi 3+ (r = 1.24 Å) ions replacing the La 3+ (r = 1.22 Å) and Pr 3+ (r = 1.13 Å) ions have nearly the same or close ionic radii r [11].…”

Correlation between magnetic and electric properties based on the critical behavior of resistivity and percolation model of La0.8Ba0.1Ca0.1MnO3 polycrystalline

“…have been widely studied to understand the physics behind their properties and to explore their practical applications. [1][2][3] La 1Àx Ca x MnO 3 compounds have drawn much attention because of their enormous magnetoresistance (MR) and magnetocaloric effect (MCE). This makes them good candidates for a wide variety of applications.…”
