Abstract
The effects of a high magnetic field on the interdiffusion behavior at liquid Bi/solid Bi04Sb06 interface have been experimentally investigated It was found that the migration of the interface due to interdiffusion decreased markedly with the increasing strength of magnetic field This was relevant to the increasing of the viscosity in the liquid metal under a high magnetic field which in turn caused diffusion activation energy to increase As a consequence in the presence of a high magnetic field a considerable decrease in the effective diffusion coefficient occurred Moreover the retarding effect of magnetic field gradient on diffusion was found to be more significant than that of a uniform magnetic field
