摘要：

We propose a path integral method to investigate the quantum spin dynamics. A centroid with spin is introduced as an average spin coordinate of a closed isomorphic necklace of each spin space, so-called a spin centroid. We calculate the magnetization of a system with total spin 1 and observe magnetic quantum tunneling with magnetic field.
