用非弹性中子散射法测量了各向异性反铁磁材料在磁渗透阈值浓度及略高于阈值浓度时的低温激发。用局域的经典激励模型模拟了这些激发，该模型很好地解释了散射实验中观测到的激发的能量和相对强度。
The low temperature excitations in the anisotropic antiferromagneticforand, at and just above the magnetic percolation threshold concentration, were measured using inelastic neutron scattering. The excitations were simulated forusing a localized, classical excitation model, which accounts well for the energies and relative intensities of the excitations observed in the scattering experiments.
