Magnetization and Electrical Resistivity in Itinerant Electron Ferromagnet Ni3Al

The temperature dependence of the magnetization, electrical resistivity and magnetoresistance of the stoichiometric Ni 3 Al have been measured. The spontaneous magnetization under the zero magnetic field and temperature T , M (0, T ) has a temperature dependence in a form of M (0, T ) 2 ∝ T 4/3 in a wide temperature range. The electrical resistivity shows a T 5/3 -dependence in a temperature range below and above T c . These experimental results are consistent with the predictions of the self-consistent renormalization (SCR) theory of spin fluctuations. The experimental results of the magnetoresistance are also discussed with the SCR theory.
