(a) The temperature dependence of resistivity, the inset shows ln ρ versus 1/T. (b) The magnetic susceptibility χ as a function of temperature under ZFC and FC conditions and the reverse susceptibility versus temperature. The red line is the fit of Curie–Weiss law between 200 K and 300 K. The inset shows the low temperature parts.
