Antiferromagnetic Transition in \alpha-Mn-Fe System

Authors: R. K. NKUM, F. BOAKYE

Abstract: Antiferromagnetic transition in $\alpha$-Mn-Fe alloys has been studied using resistivity-temperature measurements from 300 to 1.5 K. The results indicate that the transition temperature $T_N$ of the samples studied increases with increasing Fe concentration. This suggests that the N\'{e}el temperature is affected by Fe. Also, Fe plays a significant role in the local disorder on the magnetic moment of the ions in the complex manganese structure.

Keywords: resistivity, antiferromagnetic transition, magnetic moment, disorder.
