摘要：

We model the charge, spin, and heat currents in ferromagnetic metal vertical bar normal metal vertical bar normal metal trilayer structures in the two current model, taking into account bulk and interface thermoelectric properties as well as Joule heating. The results include the temperature distribution as well as resistance-current curves that reproduce the observed shifted parabolic characteristics. Thin tunneling barriers can enhance the apparent Peltier cooling. The model agrees with the experimental results for wide multilayer pillars, but the giant effects observed for diameters less than or similar to 100 nm are still under discussion.
