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 similar to 110 mJ mol(-1) K-2, is enhanced; three magnetic transitions, with critical temperatures of approximate to 7, approximate to 5 and approximate to 4K 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 1.2 mu(B), saturated moment.
