a Temperature dependence of magnetization in the La0.9Sr0.1MnO3 samples. Insets: (i) the dM/dT vs. T plots, and (ii) dependence of TC on the average of grain size (d). b Saturation magnetization Msat values versus the inverse of the crystallite sizes (1/d). Insert in (b) is a schematic diagram of the core-shell model for ferromagnetic nanoparticle. Reproduced with permission [148]. Copyright 2014, Elsevier Ltd and Techna Group S.r.l
