概要
- 論文の詳細を見る
We report resistivity $\rho$ and Hall effect measurements on EuFe2As2 at ambient pressure and 28 kbar and magnetization measurements at ambient pressure. We analyze the temperature and magnetic-field dependence of $\rho$ and the Hall effect using a molecular-field theory for magnetoresistance and an empirical formula for the anomalous Hall effect and find that electron scattering due to the Eu2+ local moments plays only a minor role in determining electronic transport properties of EuFe2As2.
