Enhanced Giant Magnetoimpedance in Co-based Microwire by Pluse Nd:YAG laser
펄스형 레이저를 비정질 와이어 거대 자기교류저항전류 향상
Abstract
The influence of laser annealing on gaint magnetoimpedance effect of glass-covered Co-based amorphous microwires is investigated by illuminating pulse Nd:YAG laser on the etched microwires. The maxium GMI ratio reaches maximum of around 85 % at the frequency of 5 MHz for the sample iluminated by the pulse with laser energy fo 132 mJ/pulse.
