Effect of Sn-doping on the structural, magnetic and magnetocaloric properties of La0.67Ba0.33Mn1−xSnxO3 compounds

Magnetocaloric effect (MCE) in fine-grained perovskite manganites of the type La0.67Ba0.33Mn1−xSnxO3 (x=0.05, 0.1 and 0.15) were prepared by the solid-state method. The prepared samples remain single phase and exhibit paramagnetic to ferromagnetic phase transition (T
