On the non-uniqueness of optimum thickness for the magnetic coating layer of NiFe/Cu composite wires

摘要

In the development of composite wires for magnetic or Magneto-Impedance (MI) effect sensors, one critical factor affecting the performance of such wires is the thickness of the magnetic layer. Atalay showed [1] that within their studied thickness range (1-10μm) for the deposited magnetic layer, a larger thickness resulted in higher MI%.
