Magnetic Properties and Giant Magnetic Impedance of Amorphous CoFeNISiB Ribbons in the Form of Micromeanders

Microstructures in the form of meanders are widely used as elements of magnetoresistive and magnetoimpedance (MI) sensors. In this paper, for the structures of the “microstrip line” type and the N-shaped meanders prepared from amorphous CoFeNiSiB ribbon, the MI effect is studied in the longitudinal (LMI) and transverse (TMI) configurations. The LMI effect reaches 180%, which is significantly higher than in the case of tapes of the same size (5 mm) without microstructuring.
