The magnetoresistance in GdNi: Magnetic-polaronic-like effect near Curie temperature and low temperature sign reversal

R. Mallik, E. V. Sampathkumaran, P. L. Paulose +1

The results of magnetoresistance ($\Delta \rho /\rho$)measurements in GdNi, in the temperature range 4.2 to 300 K are reported. The sign of $\Delta \rho /\rho$ above the Curie temperature (Tc= 70 K) is nega…
