Description

Single-crystalline, body-centered-cubic Fe films have been electrodeposited on n-GaAs (001)- (111)-, and (110)-oriented substrates from ferrous ammonium sulphate [Fe(NH4)2SO4] electrolytes. The purity of the epitaxial Fe films (lattice constant), and the quality of the epitaxy as indicated by x-ray diffraction and transmission electron microscopy, is comparable to vacuum-deposited films. The films nucleate as islands that strain relax before coalescing into continuous layers. The resulting interfaces are atomically abrupt and the films are magnetic with easy magnetization axes the same as that for bulk iron
