manganites (, Ga, Fe, Mn, and In): Local structure and electron configuration effect on Curie temperature and magnetization

Effect of Al substitution on magnetocaloric effect in La0.57Nd0.1Sr0.33Mn1−xAlxO3 (0.0≤x≤0.30) polycrystalline near room temperature

“…Earlier studies have shown that with decreasing the mean radius of B-site r B , the T C decreases and results in an enhancement of a spin lattice interaction [32]. As it can be seen from Ref.…”

Synthetic Methods for Perovskite Materials; Structure and Morphology

“…The hole-doped perovskite manganese oxides with general formula Ln 1-x A x MnO 3 (Ln= La, Pr, Nd; A= Ca, Sr, Ba, Pb; x<0.5) draw considerable attention in the late 1990´s due to their colossal magneto-resistance (CMR) effect at low temperatures . In the search for new CMR materials it was observed that doping on Mn site by other transition metal elements, such as Cr, Fe, Co and Ni, was an effective way to obtain new materials, which also helped to understand the new phenomenon (Tai, 2000;Takeuchi, 2002;Ulyanov, 2007). Phase morphology, highly dependent on preparative conditions, was also observed to play an important role in the effect: low temperature CMR was improved as the grain size was reduced (Das, 2002).…”

Comparing study of magnetic‐ion and nonmagnetic‐ion doping effect at Mn site in La0.825Sr0.175MnO3 compound

“…Most experiments reveal that the Mn site doping will weaken the long‐range FM ordering resulting in the decrease of Curie temperature. Moreover, magnetic and nonmagnetic ions doping at Mn sites always have a different effect 17. It should be noted that the previous Mn‐site doping works have mainly focused on FM metallic compounds such as La 0.7 Sr 0.3 MnO 3 .…”
