| 摘 要： | 采用高频感应加热熔融拉引法制备Fe73.0Cu1.0Nb1.5V2.0Si13.5B9.0 非晶玻璃包裹细丝，经适当温度退火处理得到纳米微晶丝。首次研究了样品在纵向驱动方式下的巨磁阻抗效应，发现T=570℃下退火得到的样品，在驱动电流频率f=300kHz时其最大磁阻抗变化可达1020%.

| Abstract: | Amorphous Fe73.0Cu1.0Nb1.5V2.0Si13.5B9.0 microwires were prepared by glass-coated melt-spinning technique. Nanocrystalline samples were obtained by annealing the amorphous wires at appropriate temperatures and the longitudinally driven giant magneto-impedance effect has also been investigated for the first time. The result showed that the maximal magneto- impedance value was 1020% obtained in the sample annealed at 5700℃. |
