Abstract
Ferrites films are of particular interest in the design of high frequency microwave devices, such as isolators, cilculators, and phase shifters because of their large resistivity and high pemeabilities. To date, most of these devices employ bulk ferrite components or require post-deposition heat treatment to obtain the spinel structure. In this report, we have fabricated Fe3O4 and CoFe2O4 ferrite film, with epitaxial quality, on MgO(001) substrate by molecular beam epitaxy. The x-ray diffraction patterns of both samples show inverse spinel structure. The magnetic measurements are carried out by a SQUID magnetometer. Figure shows the hysteresis curves at 25K and 300K for both samples.
