摘要：

A detailed study of the magnetic properties of the hexagonal NdGa2 compound has been made, by using specific heat, resistivity and magnetization measurements as well as elastic and inelastic neutron scattering experiments, on polycrystalline material and on a single crystal. The main features are: (i) the presence of two distinct and successive incommensurate-like magnetic structures below T-N = 9.5 K; (ii) the growth of a small ferromagnetic component at low temperature; (iii) multistep behaviour in the magnetization processes. Complex H-T phase diagrams have then been deduced along the three main symmetry directions. From the whole set of experiments, the crystal field and exchange parameters have been determined.
