Abstract

The magnetoimpedance (MI) effect was studied in single-layered (Fe73.5Cu1Nb3Si15.5B7) and sandwiched (Fe73.5Cu1Nb3Si15.5B7/Cu/Fe73.5Cu1Nb3Si15.5B7) thin films. Both single-layered and sandwiched structures were deposited onto glass substrates using the high-power impulse magnetron sputtering (HiPIMS) discharge operated with ultra-short pulses (3 μs). The MI measurements have been performed at room temperature, at frequencies up to 500 MHz, in longitudinal and transverse magnetic fields, before and after thermal / thermo-magnetic treatments. The largest MI ratio was obtained at 100 MHz, for the sandwiched structure, under the action of a longitudinal external magnetic field, after a thermo-magnetic treatment performed at 290oC.
