Magneto-impedance and Magnetic Sensitivity of FeCoSiB Nano-crystalline Micro-wires under Applied Longitudinal Stress

The study examined the effect of longitudinal stress on the magneto-impedance (MI) and magnetic sensitivity of FeCoSiB nano-crystalline micro-wires at frequencies from ۰.۵ to ۸ MHz. Results showed that longitudinal stress significantly enhanced MI, with the highest MI response of ۱۸۹% at ۳ MHz and ۷۰ MPa stress. This method is proposed as a cost-effective and efficient approach for designing stress sensors using the giant magneto-impedance effect.
