用射频溅射法制备了Fe73 .5Cu1Nb3Si13.5B9 单层膜和Cu 或Ag 作为中间层的三明治膜.溅态膜为非晶态结构.磁畴观察结果表明,单层膜在380 ℃退火后,呈现均匀磁化的纳米晶结构,该样品软磁特性最佳,其巨磁阻抗效应最大,在13 MHz ,最大磁阻抗比纵向为18 % ,横向为14 % .溅态三明治膜具有较大的巨磁阻抗效应,在13 MHz ,Cu 夹层三明治膜的最大磁阻抗比纵向为32 % ,横向为11 % ,Ag 夹层三明治膜的最大磁阻抗比纵向为47 % ,横向为57 % .Cu夹层三明治膜经250 ℃退火后,在低频下表现为巨磁电感效应,在100 kHz,最大磁电感比为1733 % .
Fe73 was prepared by RF sputtering. 5Cu1Nb3Si13.5B9 monolayer film and Cu or Ag as an intermediate layer. Spraying film is amorphous structure. The results of magnetic domain observation show that the single-layer film exhibits a uniform magnetized nanocrystalline structure after being annealed at 380 ° C. The sample has the best soft magnetic property and has the largest GMR effect. At 13 MHz, the maximum magnetic resistance is 18% , Horizontal 14%. The maximum GMR of Cu sandwiched sandwich membrane was 32% in the longitudinal direction and 11% in the horizontal direction at 13 MHz. The maximum magnetic resistance of the sandwich sandwich membrane was 47% 57% horizontally. The Cu sandwich sandwich films annealed at 250 ℃ exhibited giant magneto-inductive effect at low frequency, and the maximum magneto-inductive ratio was 1733% at 100 kHz.
