Effect of Pressure on the Electrical Resistivity of Fe₆₅(Ni_0.84Mn_0.16)₃₅ Alloy

Abstract

The electrical resistivity of Fe₆₅(Ni_0.84Mn_0.16)₃₅ alloy is measured under high pressure up to 30 kbar from 4.2 K to 300 K. A resistance minimum is found near 25 K at atmospheric pressure. The temperature of the resistance minimum is appeared not to depend on pressure. Isothermal resistivity shows anomalous behaviors against pressure below 150 K. These results suggest the existence of a pressure induced magnetic phase transition at low temperature.
