Cuprous oxide microcrystals were formed on stainless steel and ITO substrates by cathodic deposition of a nitrate bath with and without SDS (NaC12H24O4S) as a surfactant agent. The influence of high magnetic field on the tunable morphology of Cu2O was studied. It was shown that without SDS, the morphology of cubic crystals changes from dense to very a high porous crystal with a high magnetic field (12 T) and to a labyrinthine type structure for an intermediate field (6 T). With SDS, a fractal type growth is generated with branching in more numerous directions under a magnetic field due to modification in adsorption of SDS under magnetically induced convection.
