Development of Thin Soft Magnetic Amorphous Microwires for High Frequency Magnetic Sensors Applications

摘要：

In this paper we report novel results on hysteretic properties and GMI effect (diagonal and off-diagonal components) at high frequency region (between 10MHz and 500 MHz) in thin amorphous microwires (Fe-rich, Co-rich and Co-Fe-rich with nearly-zero magnetostriction constant) with metallic diameter between 5 and 15 μm. Control of the samples composition and geometry allows to tailor their magnetoelastic anisotropy and respectively magnetic softness and GMI. On the other hand special thermal treatment allows inducing the magnetic anisotropy by stress and/or magnetic field annealing. Such induced anisotropy allows achieving better magnetic softness, stress and temperature sensitivity. Development of novel soft magnetic microwires compositions with low Curie temperature allows obtaining temperature sensitive GMI effect.
