Abstract: The paper presents the results of a study of the magnetic field dependences of the Hall and Nernst–Ettingshausen coefficients in a wide temperature range of 10–370 K in a thin ferromagnetic CoPt film formed on a semi-insulating gallium arsenide substrate by electron beam evaporation in a vacuum. The presence of the dominant contribution of the anomalous component of the effects in the entire investigated temperature range is shown. The experimentally obtained temperature dependences of the amplitude of the effects are presented, and they are compared with the theoretical model.

Keywords: Hall effect, Nernst–Ettingshausen effect, spin-dependent scattering, scattering factor, spintronics.
