a Temperature-dependent electrical resistivity, ρ(T), at zero field. Electrical current was applied along the c-axis. Inset shows an activated log ρ vs 1/T plot. b ρ(T) in a log plot. Inset shows a zoom in the low-temperature region. c ρ(T) at various magnetic fields applied long the b-axis. Inset shows MR vs reduced magnetization (M/Ms) squared. d MR vs applied field at various temperatures.
