| Outline of Final Research Achievements |
In this study, nanowires were created from Co36Fe36B19Si5Nb4 amorphous alloy, which is a soft magnetic material and has low coercive force and high magnetic permeability by gas atomization method. We verified the magnetic impedance effect at the nanoscale, We have been conducting research on the development of nanosized magnetic sensors. Main research results include 1) Optimization conditions of gas atomization in fabrication of nanowire, 2) Establishment of nanowire fixing method using focused ion beam, 3) Construction of prototype nano magnetic impedance sensor, 4) Detection of external magnetic field using nano magnetic impedance sensor and measurements of frequency dependence of ferromagnetic resonance, 6) Detection of impedance change depending on wire diameters.
