Study on the giant magnetoimpedance effect of FeCuCrVSiB multilayered films
Acta Physica Sinica, 2005 Giant magneto-impedance (GMI) effect of a multilayered film with the structure o f (FM/SiO2)3/Ag/(SiO2/FM)3 (FM≡FeCu CrVSiB) was studied. The multilayere d film was deposited by radio frequency sputtering onto a single crystal Si subs trate. A constant magnetic field of about 72kA/m was applied along the longitudi nal direction of the film plane ...
