Electrical Resistivity of Nickel Near the Curie Point

Abstract

Emphasis is placed on the temperature dependence of the magnetic resistance ${R}_{\mathrm{mag}}$ in the region ${10}^{\ensuremath{-}4}\ensuremath{\lesssim}|\ensuremath{\epsilon}|\ensuremath{\lesssim}{10}^{\ensuremath{-}2}$, where $\ensuremath{\epsilon}=\frac{(T\ensuremath{-}{T}_{c})}{{T}_{c}}$. The temperature dependence of $\frac{d{R}_{\mathrm{mag}}}{\mathrm{dT}}$ is found to be the same, within experimental error, as that of the specific heat, both above and below ${T}_{c}$. The anomalous behavior in the region $0\ensuremath{\lesssim}\ensuremath{\epsilon}\ensuremath{\lesssim}5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$ reported by Craig, Goldburg, Kitchens, and Budnick is not observed.
