Low-temperature resistivity and magnetization of a CeCo2Si2 single crystal

Abstract Low-temperature resistivity down to 0.3 K and temperature and magnetic field dependence of magnetization have been measured on a CeCo 2 Si 2 single crystal. It has been revealed that the physical properties are well characterized as a valence fluctuating system and there is no indication of superconductivity down to 0.3 K.
