We have explored spin-dependent hot electron transport in a magnetic tunneling junction at finite temperatures. The inelastic mean-free path has been extracted from either theoretical calulations or experimental measurements. The temperature dependence of hot electron spin polarization has been modeled according to P[SUB0][1-(T/T[SUBc])[SUP3/2]]. The bias dependence of magnetocurrent agrees in trend with experiments, which indicates that the model adopted here indeed displays the key factors in these phenomena.
