有机磁性材料的极化中子衍射实验揭示了磁性分子单元内自旋密度的高度偏斜分布。观察到的效应的非常大的幅度是由于量子自旋波动。的数据是在定量协议与直接对角化结果的模型自旋哈密顿量，并提供洞察力的实际微观起源相关的交换相互作用。
Polarized neutron diffraction experiments on an organic magnetic material reveal a highly skewed distribution of spin density within the magnetic molecular unit. The very large magnitude of the observed effect is due to quantum spin fluctuations. The data are in quantitative agreement with direct diagonalization results for a model spin Hamiltonian, and provide insight on the actual microscopic origin of the relevant exchange interactions.
