Abstract
Magnetic and structural properties of gamma iron oxide thin films depe nd significantly on the orientation of the substrate with respect to t he direction of source vapour during the growth of films by the reacti ve chemical vapour dissociation technique. Formation of large grains a nd grain clusters is observed for flat deposited films as compared wit h compact small grains at oblique incidence. Such structural variation modifies the anisotropy in the film, resulting in high coercivity of 770 Oe and remanence of 2.7 kG in undoped gamma-Fe2O3 films.
