Abstract

The magnetic properties and surface morphology of CoFeNi alloy films electrodeposited under external magnetic field were investigated. It was observed that crystallographic anisotropy in CoFeNi films was induced due to the preferential orientation of applied magnetic field. In addition, the CoFeNi alloy films showed excellent magnetic property (low H c), which is considered that not only the smaller grain size of the films, but also more uniform surface of the films than that deposited in absence of applied magnetic field. These observed phenomena could be explained with magneto-hydrodynamic (MHD) convection of charged ions at the interface of electrode and electrolyte induced by Lorentz force.
