【 摘 要 】

We present transport and thermodynamic measurements as a function of temperature (0.1-300 K), pressure (1 bar-16 kbars), and magnetic field (0-600 kOe) on YbInNi4. Ferromagnetism arises near 3 K out of a state with enhanced electronic specific-heat coefficient. Resistivity, specific-heat, and magnetization measurements imply that the ground state of YbInNi4 is a crystal-field doublet, whereas earlier neutron-scattering results suggest a ground-state quartet. We also compare YbInNi4 to YbInCu4 and intermediate alloys.
