A new and unique Eu-based mixed valence system: EuPd₂Si₂

Abstract

Reports the results of studies on a new and a very interesting intermediate valence (IV) material EuPd2Si2, which exhibits some unique features not observed so far in any Eu-based IV system. The magnetic susceptibility exhibits a very clear maximum and the isomer shift shows an unusually large temperature dependence in the interval 120-200K.
