STRUCTURE AND MAGNETISM OF DC-MAGNETRON SPUTTERING Fe / Ti PERIODICAL NANO-MULTILAYERS
磁控溅射制备Fe／Ti多层膜的结构和磁性

A series of Fe/Ti periodical nano-miltilayers was prepared by DC-magnetron sputtering. The modulation period is between 2.2 and 24 nm. The structure of the specimens was examined by TEM and small-or high-angle X-ray diffraction technique. Their magnetism was also studied by the vibratory sample magnetometer and Mossbauer spectrum. The face-centred cubic Fe was found in multilayers containing thinner Fe layers nearby 2 nm. The saturation magnetization increases and the coercivity decreases with increasing modulation period.
