Effects of high uniform magnetic fields on diffusion behavior at the Cu/Al solid/liquid interface

Interdiffusion experiments of Cu and Al were carried out under a high magnetic field of up to 12 T. It was observed that uniform magnetic fields exerted a non-monotonic influence on the thickness of diffusion layers. This phenomenon could be attributed to the effects of high magnetic fields suppressing natural convection and inducing thermo-electromagnetic convection at Cu/Al solid/liquid interface.
