Abstract
Temperature dependence of the resistivity, Hall coefficient and magnetic susceptibility of HfTe5 with 1.5 wt. %, Zr is reported. Anisotropic large diamagnetism is reported and has the peak in the vicinity of 76 K. Temperature dependence of Hall coefficient under 117 kOe elearly shows the destruction of Fermi surface at about 90 K. HfTe5 can be considered to be a semimetal and observed resistivity anomaly may be accompanied by the CDW formation along c-axis. We also discuss the mixed crystal effect with ZrTe5 and present the data of quantum oscillation observed at low temperature.Keywords
