Magnetic electrodeposition

Magnetic electrochemistry is reviewed, with emphasis on the physical mechan isms involved. Magnetic fields can be used during electrodeposition to enha nce the deposition rate of magnetic or non-magnetic species, and also to in duce turbulence. Theses effects are attributed to field-induced convection which creates a transverse flow that disrupts the depletion layer near the electrode. The morphology of radially grown electrodeposits is especially s ensitive to magnetic fields when the Lorentz force interferes with natural convection. Electrodeposition is also useful for preparing ferromagnetic th in films, multilayers and nanowires. (C) 2001 Elsevier Science BY All right s reserved.
