| Research Abstract |
Multiplication effect of ferromagnetic/ferroelectric composite for application of multi-ferroic magnetic sensor with high sensitivity was investigated and a micro device was fabricated. Magnetic sensor designed by magnetostrictive FeSiB(50 μm) film /PZT(C-3)/ FeSiB(50μm) three layers outputted high voltage at a resonance frequency, 74 kHz. While, the sensor exhibits same sensitivity in AC frequency range of 0.001Hz～100Hz and can analyzes low magnetic field of 0.001 Oe in a range of 0.1Hz～100Hz. Micro cantilever sensor of FePd film/Si(10 μm) by MEMS fabrication process exhibited sensibility of 0.15-0.6μm/Oe in low magnetic field under 30 Oe.
