Abstract :
Magnetization of a series of epitaxial Fe3O4/MgO multilayers grown on MgO(100) substrates by oxygen-plasma-assisted molecular-beam epitaxy has been studied. The Curie temperature decreases with decreasing the thickness of each Fe3O4 layer. The saturation magnetization of all the multilayer samples seems to be lower than that of the 200 nm thick Fe3O4 film
