摘要: Abstract We performed polarized neutron scattering experiments in lightly-doped La 1.982 Sr 0.018 CuO 4 , which shows both Neel ordering and spin-glass state at low temperatures. Three-dimensional polarization analysis was on diffuse magnetic peaks the phase. From analysis, we concluded that ratio of spin components along a b c axes is 0.8, 1.0 0.15, respectively, indicating energy fluctuations ( | E 1.7 meV ) have XY anisotropy.
