摘要：

The spin ordering of La3/2Sr1/2NiO4 was investigated by magnetization measurements and by unpolarized- and polarized-neutron diffraction. Spin ordering with an incommensurability epsilonapproximate to0.445 is observed below T(SO)similar to80 K. On cooling, a spin reorientation is observed at 57+/-1 K, with the spin axes rotating from 52degrees+/-4degrees to 78degrees+/-3degrees.
