Abstract

We propose a new simple method to directly apply dc current to the CoNbZr/Cu film of a sensor. A very sensitive thin film sensor was developed using a meandering coplanar line with biasing conductors fabricated from SrTiO film (0.75 μm thick), amorphous Co85Nb12Zr3 film (1.0 mm × 2.45 mm, 1 μm thick) and Cu/Cr film (2 μm/0.1 μm). We discuss direct bias to CoNbZr film and Cu film under a CoNbZr film and compare it with an application of bias magnetic field. Good sensitivity (phase change over 100 degrees/Oe) was obtained by the proposed method.
