The ternary silicides RE6T1:67Si3 (RE = Ce, Pr, Nd, Gd, Tb and T = Co, Ni) crystallizing with the hexagonal Ce6Ni1:67Si3-type structure has been recently extensively studied. It has been shown that some of these compounds exhibit interesting magnetocaloric properties. In this work, the magnetic structures of the Nd6Ni1:67Si3 compound were determined by means of neutron powder di®raction. According to previous magnetization and speci¯c heat measurements, this compound exhibits two successive magnetic transitions at 84K and 38K. The ¯rst transition corresponds to a ferromagnetic arrangement of the Nd-moments along the c-axis and the second one to a non-collinear ferromagnetic arrangement yielding a conical structure. The magnetic structures of Nd6Ni1:67Si3 are compared to those of the Nd6Co1:67Si3 homologous ternary silicide.< Réduire
