Magnetization curves of single crystals were measured from 4.2 K up to T.(:30 K). The magnetization is approximately expressed by M=M,-f-z.H inhigher fields. '7,. which reflects the antiferromagnetic character, was found to bealmost isotropic and temperature-independent (:8 x 10 ' emu/g). Aug is aniso-tropic; 0.97 emu/g (0.02 p./Ni) along [001] and 0.69 emu/g along [1104 at 4.2 K.The magnetic field effect on the intensity of neutron diffraction was examined onsingle crystals. Any appreciable effect was not found within experimental errorson two antiferromagnetic reflections. An improved model (model 3) for the spinstructure is proposed, which explains the observed intensities of neutron diffrac-tion, M6ssbauer study and the behavior of z...
