Abstract
In the model of quantum tunneling of domain walls in ferromagnets given by Chudnovsky et al., the crossover from quantum tunneling to classical hoppin g is investigated. Considering the periodical boundary condition of spatial coordinate, the type of transition depends critically on the length of fer romagnet along the Y-axis. (C) 2001 Elsevier Science B.V.
