High-Temperature Behavior of the Resistivity in Nearly Magnetic Metals: Application to Plutonium

Abstract

We show that, in nearly magnetic metals, taking into account the temperature dependence of the Stoner susceptibility makes the electron-paramagnon electrical resistivity depart from the usual low-temperature $T^2$ and $T$ power laws at temperatures higher than the spin-fluctuation one. A high-temperature plateau is expected and a maximum may arise at lower temperature depending on the parameters. Possible fits are presented for the resistivities of Pu and Np.
