✦ Synopsis

Neutron diffraction experiments were carried out to determine the magnetic structure of Nd 7 Ni 3 in an external field. At 4.2 K and in external fields below 1.3 T the magnetic structure is conical with a basal plane helical component having a propagation vector Q (0, 0, 1/3) and a c-axis ferromagnetic component. Above 1.3 T the c-axis component disappears, while the basal plane component remains up to 2.7 T. Below 0.3 T, the magnetic structure changes from conical to helical at about 8 K. A rough (H, T) phase diagram is given and is generally consistent with the results of magnetization measurements.
