Low-field (B=2-80G) dc magnetic susceptibility, χ, investigated in hole-doped La 1 - x Ca x Mn 1 - y Fe y O 3 (LCMFO) with x=0.3 and y=0.05-0.10, exhibits non-uniform critical behavior near the paramagnetic (PM)-to-ferromagnetic (FM) transition temperature, T C . We observe the scaling law, χ - 1 (T)-χ - 1 (T C )~(T/T C -1) γ =τ γ , with γ~1.4 corresponding to a 3D Heisenberg spin system below τ c r ~0.1-0.2, and with γ~1.7 characterizing a 3D percolation system, above τ c r . The non-universal scaling results from strongly inhomogeneous distribution of holes leading to formation of percolation clusters from the hole-rich nanoscale FM particles, embedded in the host PM matrix.The resistivity, ρ, of LCMFO exhibits between a temperature T v ~310-330K and T C the Shklovskii-Efros-type variable-range hopping conductivity law, ρ(T)=ρ 0 (T)exp[(T 0 /T) 1 / 2 ], governed by generation of a complex gap in the density of states. The prefactor follows the law ρ 0 (T)~T m , where m changes from 9/2 at y=0 to 5/2 at y=0.03, 0.07 and 0.09, reflecting an additional fluctuating short-range potential induced by doping with Fe.
