Effect of ZnO Thin layers on Magneto-impedance Response and Field sensitivity of Co-based Micro-wires

ZnO layers (۸۷-۵۰۰ nm) were deposited on Co-based micro-wires via magnetron sputtering to study their magnetoimpedance (MI) response. The MI% improved with ZnO thickness, peaking at ۴۰۶% and ۴.۹۹%/Oe sensitivity at ۲۴۰ nm. Characterizations (XRD, SEM, and VSM) confirmed that ZnO coatings enhance MI response and sensing performance.
