| 摘 要： | 用化学镀的方法制备了镀NiFeCoP膜的复合结构丝,这种复合结构丝在较低频率下就有较好的磁阻抗效应.对样品进行电流退火处理,不同电流密度退火对复合结构丝磁阻抗效应特性的影响不同.利用复数磁导率探讨了该复合丝在不同电流密度退火后的磁化过程和磁化频率特性,较大电流密度退火后复合结构丝的畴壁运动被抑制,减弱了动态磁化过程,降低了相应的磁阻抗效应.

| Abstract: | NiFeCoP/CuBe composite wires were produced by electroless-deposition.The composite wires have distinct magneto-impedance effect at low frequency.Thermal treatments by DC Joule annealing were applied to the composite wires for a fixed annealing time.The influence of DC Joule annealing on magneto-impedance effect was studied.The magnetization in NiFeCoP composite wires was analyzed in terms of complex permeability.The results show that the domain wall of composite wires was damped after annealed in higher current density,and the magneto-impedance effect was also reduced. |
