Temperature dependence resistivity of the La0.7Sr0.3MnO3 (LSMO) nanoparticles with zero field and 1 T fitted by using ρ(T) = ρ0 + ρ2T2 + ρ4.5T4.5. a LSMO-1 particles (average size of 20 nm), b LSMO-2 particles (average size of 23 nm), and c LSMO-3 particles (average size of 26 nm). Inset shows the fitting of the resistivity data in the low temperature region by using \( {\rho}_L={\rho}_0-{\rho}_s\ln T+{\rho}_e{T}^{\frac{1}{2}}+{\rho}_p{T}^5 \).
