Abstract

Detailed anisotropic resistivity and heat-capacity measurements down to $\sim 0.4 K$ and up to 140 kOe are reported for a single crystalline YbAgGe. Based on these data YbAgGe, a member of the hexagonal RAgGe serie, can be classified as new, stoichiometric heavy-fermion compound with two magnetic ordering temperatures below 1 K and field-induced non-Fermi-liquid behavior above 45–70 kOe and 80–110 kOe for $H ‖ ab$ and $H ‖ c,$ respectively.
