Abstract
PURPOSE:To obtain an artificial magnetic lattice film which exhibits a high saturated magnetic flux density and good soft magnetic characteristics, also has a magnetostriction constant substantially equal to zero, and simultaneously is excellent in corrosion resistance and thermal stability, by alternately stacking on a substrate a Fe layer and a Co layer and/or a CoFe layer so that they have a periodic structure by repetition. CONSTITUTION:Four targets can be mounted on a target supporting stand 1, which can be rotated to switch the targets. There are a position at which a substrate is to be placed, on the upper surface of which substrate magnetic films are to be stacked and formed, and an ion source 3. The manufacture by an ion beam sputter method is advantageous in that the operating degree of vacuum is 1X10<-4>Torrs or less and the substrate temperature does not increase more than required. A Co layer 4, Fe layer 6, and CoFe layer formed by mutual diffusion are formed on a substrate 7. The film thicknesses of the Co layer 4 and Fe layer 6 are tCo and TFe, respectively, and one period tP of the artificial lattice is defined by an equation tP=tCo+tFe. The artificial magnetic film can thus accomplish good soft magnetic characteristics and simultaneously can achieve a high saturated magnetic flux density. Also, these magnetic artificial film has a construction wherein Fe is with respect to Co and/or CoFe, so they are rich in corrosion resistance and the magnetic characteristics are not degraded, providing excellent thermal stability.
