| Popis: | FePt films were rf sputtered at room temperature and 550˚C on MgO monocrystalline substrates. Room temperature films were post-annealed at 550˚C. The high temperature growth induces a tetragonal distortion of the structure with the formation of L10-FePt phase. Soft iron layers, with different thickness, were e-beam deposited on these hard films. The phenomena occurring at the interface have been analysed and connected with the final magnetic behaviour of the system. It has been found that a strong exchange coupling between soft and hard layers has been established through the formation of an interfacial layer constituted by FePt small particles. |
