Magnetic heterostructure nanowires with three different compositions (i.e. Au–NiO–Au, Ni–NiO–Ni, and Au–Ni–NiO) were successfully fabricated via simple chronoamperometric technique of the electrochemical deposition. Morphologies and compositions of the prepared samples were analyzed by the field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and x-ray diffraction (XRD), respectively. Magnetic properties of the fabricated nanowires were measured with the help of superconducting quantum interface device (SQUID) in a temperature range (2 K–300 K). The temperature dependent magnetic properties indicate that the heterostructure nanowires are composed of the superposition of ferromagnetic, anti-ferromagnetic components and exhibiting superparamagnetism and spin-glass like behaviors in different temperature range. Low temperature magnetization reveals high anisotropy of the prepared samples and showing high magnetization at the Ni/NiO interface of the nanowires. These nanostructures might have potential applications in the memory devices.

通过简单的电化学计时电化学方法成功地制造了具有三种不同成分（即Au–NiO–Au，Ni–NiO–Ni和Au–Ni–NiO）的磁性异质结构纳米线。分别通过场发射扫描电子显微镜（FESEM），透射电子显微镜（TEM）和X射线衍射（XRD）分析所制备样品的形态和组成。借助超导量子接口设备（SQUID）在温度范围（2 K–300 K）中测量了所制备纳米线的磁性。与温度有关的磁性能表明，异质结构纳米线由铁磁，反铁磁成分的叠加组成，并在不同温度范围内表现出超顺磁性和自旋玻璃状行为。低温磁化强度显示出所制备样品的高各向异性，并且在纳米线的Ni / NiO界面处显示出高磁化强度。这些纳米结构可能在存储设备中具有潜在的应用。
