Figure 9

Temperature dependence of the FC Eu-related molar susceptibility \( \chi_{m}\) (Eu) for the (a) La0.70Eu0.30FeO3 and (b) La0.70Eu0.30Fe0.95Cr0.05O3 nanoparticles, obtained by subtracting the molar susceptibility contribution of the LaFeO3 nanoparticles from that of the La0.70Eu0.30FeO3 and La0.70Eu0.30FeO3 ones, respectively, measured in an applied field of 50 kOe. The solid line represents the best fitting line based on Eqs. (1) and (2).
