Abstract

We present data on the anisotropic magnetic properties, heat capacity and transport properties of CeGe2-x (x = 0.24) single crystals. The electronic coefficient of the heat capacity, gamma ~ 110 mJ/mol K^2, is enhanced; three magnetic transitions, with critical temperatures of ~ 7 K, ~ 5 K, and ~ 4 K are observed in thermodynamic and transport measurements. The ground state has a small ferromagnetic component along the c - axis. Small applied field, below 10 kOe, is enough to bring the material to an apparent saturated paramagnetic state (with no further metamagnetic transitions up to 55 kOe) with a reduced, below 1 mu_B, saturated moment.
