摘要：
The impact of FeNi magnetic conductive coating on the high frequency impedance of Co64Fe3Cr3Si15B 15 amorphous ribbons and its dependence on an external magnetic field's strength and temperature is studied. It is shown that the coating affects the range of the magnetic field with the greatest change in the impedance of the external magnetic field, along with the temperature sensitivity of the impedance modulus and its components in the region of phase transition. The considerable differences between the properties of amorphous ribbons and CoFeCrSiB/FeNi composites found in this work allow us to evaluate the prospect of future studies aimed at developing magnetoimpedance elements for nonmarker biodetection. © 2014 Allerton Press, Inc.
