摘要:

μ子自旋弛豫方法(μSR)是一种通过观测μ子上的局域磁场分布来探测材料电子态的强有力的微观工具。局部磁场的分布常常表现出介于高斯和洛伦兹形状之间的中间状态。为了一般地描述中间场分布,我们处理了两个各向同性分布在三维空间中的卷积,并导出了精确的μ子自旋弛豫函数,该函数可以应用于高斯和洛伦兹之间的所有交叉区域。

英文摘要:

The muon spin relaxation method (μSR) is a powerful microscopic tool to probe electronic states of materials observing local magnetic field distributions on the muon. It often happens that a distribution of local magnetic fields shows intermediate state between Gaussian and Lorentzian shapes. In order to generally describe intermediate field distributions, we dealt the convolution of two isotropic distributions in the three dimension and derived exact muon-spin relaxation functions which can be applied to all crossover regimes between the Gaussian and Lorentzian.
