Recently, many studies have been carried out to develop ternary CoNiFe (cobalt/nickel/iron) and NiFe alloys due to their capacity of providing an extremely high saturation flux density and a low coercive field strength. In this study, the magnetic properties of NiFe and CoNiFe microtubes were investigated. NiFe and CoNiFe magnetic films were prepared by electrodeposition onto copper wires with a diameter of 50 μm. Coercivity of 61 A/m and a maximum MI response of 186% at a frequency of 900 kHz were obtained for NiFe, which was produced in the pH 1.8 solution. © World Scientific Publishing Company.
