Physical properties of CeGe2-x (x=0.24) single crystals.

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, γ∼110 mJ mol(-1) K(-2), is enhanced; three magnetic transitions, with critical temperatures of ≈7, ≈5 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 1.2 µB, saturated moment.
