Ferromagnetic Transitions in Ni-Mn Alloys

Authors: F. BOAKYE, R. K. NKUM

Abstract: Ferromagnetic transitions in nickel and nickel-manganese alloys have been studied using resistivity-temperature measurements from 800 to 77 K. The results establish the transition temperature of nickel as 610 K and the transition temperature is shifted to lower values as the concentration of Mn in the alloy is increased. Analysis of the resistivity results near the ordering temperature \( (T

Keywords: resistivity, transition temperature, spin disorder scattering, critical exponent.
