| Abstract: | NiFeB films were electroless-deposited on 100 μm BeCu wires and were annealed at different temperatures in N2 atmosphere. The dependence of GMI on the annealing temperature and frequencies of driving current was studied. The maximum GMI ratio of 33% of these sample was observed by annealing at 200 ℃. After adding the insulator layer between BeCu and NiFeB layer the GMI ratio of the sample increases to 83%. |
