Magnetic and Structural Properties of Iron/Amorphous Iron Alloy Multilayers

The magnetic and structural properties of ion-beam and rf sputtered Fe/amorphous Fe sub 73.3 Cr sub 6.7 B sub 20 multilayers were studied as a function of Fe and FeCrB layer thicknesses. The material is magnetically soft ( mu (10 MHz) approx 2000, H sub c < 100 A/m) and has a saturation magnetiza...

Zusammenfassung:The magnetic and structural properties of ion-beam and rf sputtered Fe/amorphous Fe sub 73.3 Cr sub 6.7 B sub 20 multilayers were studied as a function of Fe and FeCrB layer thicknesses. The material is magnetically soft ( mu (10 MHz) approx 2000, H sub c < 100 A/m) and has a saturation magnetization approx 1.8 T if the FeCrB layer thickness is > 1 nm and the Fe thickness substantially lower than the domain wall thickness in Fe, 55 nm. The magnetostriction is dependent on the ratio of Fe and FeCrB layer thicknesses. Magnetostriction close to zero can be achieved, even after annealing to 350 deg C. Domain patterns show the presence of a weak magnetic anisotropy. Graphs, Photomicrographs. 11 ref.--AA
