Low Dimensional Lattice Diffusion in Solids Investigated by Nuclear Spin Echo Measurements
摘要:
通过核磁共振自旋回波实验的数值模拟研究了固体中的晶格扩散和内部局域磁场梯度。本文采用傅里叶谱方法求解一维和二维晶格约束下具有任意磁场梯度的布洛赫-托里方程。
英文摘要:
Lattice diffusion and internal local magnetic field gradients in solids are investigated by numerical simulation of nuclear mangetic resonance(NMR) spin echo experiments. The Fourier-spectrum method is employed in order to solve the Bloch-Torrey equation with arbitrary magnetic field gradients in one- and two-dimensional lattice restrictions.
