摘　　要：采用脉冲电化学法沉积法在AAO模板上制备了钴镍铜合金纳米线,XRD测试表明纳米线有Co,Ni,NiCu和CoCu4个磁性相共存。在平行于和垂直于长轴方向上所测的磁滞回线表明:钴镍铜合金纳米线阵列具有弱的各向异性。磁性合金纳米线与石蜡的复合材料在GHz频段内具有较好的电磁波吸收性能:当吸波涂层的厚度为4mm时,其最小反射损耗可达–30dB。CoNiCu magnetic alloy nanowires were prepared in AAO templates by a pulse electrochemical deposition method. XRD measurements show that there are four magnetic phases in the nanowires, Co, Ni, NiCu and CoCu. The measured magnetic hysteresis loops taken along two directions （H is applied along or perpendicular to its longitudinal direction） show that the CoNiCu nanowire array has a weak anisotropy. The composites of magnetic alloy nanowires and wax have a good electromagnetic wave absorption property of GHz frequency. When the thickness of the absorbing coating is 4 mm, its minimum reflection loss can reach to -30 dB.
