Abstract

The spatial distribution of spin accumulation and spin current in the non-local geometry is studied taking into account the finite size effect of the contact areas by applying a finite element method in two-dimension. It is shown that, when the contacts are tunneling-like, the sign and the value of spin accumulation signal are consistent with the experimental results, and the one-dimensional analysis is appropriate to analyze the experimental results.
