摘要: The magnetic properties in the La 2 NiO 4+δ system have been investigated by 139 nuclear quadrupole resonance (NQR). structure or NQR spectrum at 1.4 K was found to depend sensitively on annealing procedures of compounds, and therefore δ. A well-characterized obtained for samples oxygenated (δ≧0.066) deoxygenated (δ∼0.022) with different structures, exhibiting existence internal fields H mt ∼17.8 kOe nearly parallel basal Ni–O plane ∼19.3 perpendicular plane. strength site significantly large when compared that ∼1 CuO 4 could not be explained simply dipole field caused Ni spin moments.
