Possible giant magnetoresistance effect in La1 − xAxMnO3 (A: Li, Na)

Electrochemical growth and properties of LaMn1−xCoxO3 (0 < x ≤ 1) single crystals

“…A positive sign of superexchange interactions in ab-planes and negative ones between them are caused by specific 2 z d -orbital ordering of the Mn 3+ ions [1]. A substitution of lanthanum by divalent alkaline [4] leads to a concentration transition to a ferromagnetic state with increasing dopant content. The ferromagnetic behavior of the doped manganates is traditionally explained in terms of the double exchange mechanism [5].…”

Perovskite-structure TlBO3 (B = Cr, Mn) for thermomechanical and optoelectronic applications: an investigation via a DFT scheme

“…[6][7][8][9][10][11][12][13][14] La 1−x B x MnO 3 (B ¼ Mn, Ca) perovskite magnates are well known to show MITs with ferromagnetic-paramagnetic transition. 15 Perovskite materials are also found to be suitable for solid oxide fuel cells. 16,17 ABO 3 is considered as an ideal perovskite material, where A is a monovalent otherwise divalent cation situated on the edges of the crystal, and B is a tetravalent or pentavalent transition metal.…”
