Ferromagnetic insulating and reentrant spin glass behavior in Mg doped La0.75Sr0.25MnO3 manganites

Switching mechanism of Al/La1−xSrxMnO3 resistance random access memory. I. Oxygen vacancy formation in perovskites

“…LSMO crystals can be tetragonal, orthorhombic, rhombohedral, or monoclinic, depending on doping level x, oxygen deciency d, and synthesis conditions. 56,85,108 LSMO at doping levels of 0.25-0.3 and 0.5 lie near the rhombohedral-orthorhombic 56,109,110 and tetragonal-orthorhombic 85,111 phase boundaries, respectively, at low temperatures. In fact their lattice constants are similar within 2% and their total energies are calculated similar within 8 meV.…”

The effect of B site doping on infrared emissivity of lanthanum manganites La0.8Sr0.2Mn1−B O3 (B = Ti or Cu)

“…Castellano et al have reported that the Cu substitution weakens in a relevant and outstanding way the FM long-range phase in the (La 1−x Ca x )(Mn 1−y Cu y )O 3 compound with x < 0.50 while the CO phase in the second class of samples (x > 0.50) results to be only slightly conditioned [15]. And the substitutions of other metal ions for Mn have also been studied [16][17][18]. Then, what about the infrared emissivity of B site doped manganites?…”

Magnetic and transport properties of cobalt doped La0.7Sr0.3MnO3

“…doped manganites due to the random distribution of the transition metal in the Mn network. [12][13][14][15] As compared to the manganites, the cobaltites have received relatively little attention. 16,17 The cobaltites have been noticed due to their unique properties, namely, the existence of spin-state transitions [18][19][20][21][22][23][24][25][26] as well as the unusual magnetic properties in the doped cobaltites.…”
