Ferromagnetic Transitions In Ni-Mn Alloys, F. Boakye, R. K. Nkum
Ferromagnetic Transitions In Ni-Mn Alloys, F. Boakye, R. K. Nkum
Turkish Journal of Physics
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
Antiferromagnetic Transition In \Alpha-Mn-Fe System, R. K. Nkum, F. Boakye
Antiferromagnetic Transition In \Alpha-Mn-Fe System, R. K. Nkum, F. Boakye
Turkish Journal of Physics
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.
