简介
Amorphous ribbons with the following compositions Co68.5Fe4.0Si15.0B12.5, Co68.6Fe3.9Mo3.0Si12.0B12.5, Co65.9Fe3.5W3.1Si16.5B11.0 and Co64.3Fe3.5W4.7Si16.5B11.0 and the same geometry were prepared by melt spinning technique despite the technological difficulties usually related to the fabrication of the tungsten containing rapidly quenched materials. The structure, magnetic properties and giant magnetoimpedance effect (GMI) measured in 0.1–100 MHz frequency range were comparatively analyzed. All of the ribbons showed soft magnetic properties but different magnetostriction coefficients, Curie temperatures, saturation magnetizations and GMI features. Both Co65.9Fe3.5W3.1Si16.5B11.0 and Co64.3Fe3.5W4.7Si16.5B11.0 ribbons showed reasonably high Curie temperature above 200 °C suitable for possible applications. Despite very small composition differences of the tungsten containing …
