  • Abstract
    The crystallinity and magnetic properties of Fe-SiO2 multilayered films are examined in the range of 7-300 Å Fe layer thickness, dFe, and 2-250 Å SiO2 layer thickness, d(SiO2). The saturation magnetization decreases steeply with dFe below 30 Å for films with d(SiO2)⩾6.3 Å owing to the change in crystallinity of the Fe layers. When d(SiO2) decreases, the magnetic hysteresis loop changes from one characteristic of in-plane magnetization to one characteristic of perpendicular magnetization as a result of the induced perpendicular anisotropy, Ku. The change in K u is explained by the variation of the magnetostatic energy stored in the layer boundaries
