We present a qualitative model study of energy and temperature dependence of hot electron magnetotransport. In this model calculation, the strong spin dependent inelastic scattering strength of hot electrons and spin mixing due to thermal spin waves have been taken into account. In addition, spatial inhomogeneity of Schottky barrier height has been considered. This calculations display that the magnetocurrent accords with the recent experimental data qualitatively at room temperature if we include the spin mixing effect with hot electron spin polarization although the experimental observation is not easy to interpret. Thus, if one measures the temperature dependence of magnetocurrent, then the mechanism suggested here will be tested whether it is acceptable.
