  摘要：

  三个新的双核螺旋结构[M 2 L 2 ]·3DMF（M = Co（II），1，Zn（II），3）和[Cu 2 L 2 ]·DMF·0.4H 2 O（2）使用helicandħ组装2大号从2结果：1之间的缩合反应Ò-香兰素和4,4'-二氨基二苯醚。双核螺旋体中的金属离子以扭曲的四面体几何形状进行四配位。Co（II）衍生物的直流磁特性和EPR光谱指向两个Co（II）中心的易轴型各向异性，两个双峰之间的间隔至少为55K。动态磁化率测量表明在施加的dc磁场中磁化速度缓慢放宽。由于钴离子之间的距离非常大（11.59Å），因此首先将其归因于每个Co（II）中心的固有特性（单离子磁体行为）。然而，Zn（II）掺杂样品中弛豫速率的温度依赖性和缓慢动力学的缺乏表明，简单的Orbach机理，拉曼或直接过程都不能解释弛豫，因此对于观察到的现象，必须调用集体现象。行为。最后，由于两个有机配体在配位时的刚性增强，纯

• Electrodeposition of Zn–Co alloys with pulse containing reverse current

  日期：2005.4

  The electrodeposition of Zn-Co alloy deposits was studied by means of pulse-plating technique. The surface morphologies of Zn-Co alloy deposits were examined using scanning electron microscopy (SEM), and an attendant energy dispersive X-ray analyser (EDA) was used to analyse the composition of Zn-Co alloy deposits. Results obtained showed that the average current density and reverse current density amongst all the variables investigated had very strong effects on the cobalt content in the Zn-Co alloy deposits. It is possible to electrodeposit Zn-Co alloy coatings with a very wide cobalt content range of 10-90 wt.% by modulating pulse parameters. Grain size, surface appearance and internal stress in the deposits were also improved significantly by introducing reverse current. (c) 2004 Elsevier Ltd. All rights reserved.

  Amorphous Co-Zn alloy nanowire arrays with diameter of about 40 nm were fabricated in anodic aluminium oxide films by the electrodeposition method Transmission electron microscope result shows that the nanowires are regular and uniform Selected area electron diffraction and X-ray diffraction results indicate that the structure of nanowires is amorphous. Vibrating sample magnetometer is employed to study the magnetic properties of nanowire arrays at room temperature. The results show that the arrays of nanowires exhibit uniaxial magnetic anisotropy with the easy magnetization direction along the nanowire axes owing to the large shape anisotropy. When the applied magnetic field is parallel to the wire axis, the coercivity and squareness of the nanowire arrays decrease with increasing Zn concentration. (C) 2009 Elsevier By. All rights reserved
• Pulse electrodeposition of Co1−xZnx nanowire arrays: Magnetic improvement through electrolyte concentration, off-time between pulses and annealing

  Using different electrolyte compositions and varying the off-time between pulses, Co1xZnx nanowire arrays were fabricated by ac pulse electrodeposition. The effect of deposition parameters on alloy contents was investigated by studying the microstructures and magnetic properties of as-deposited and annealed Co1xZnx nanowires. It is shown that Zn content in CoZn nanowires exponentially increases by increasing the zinc ions in the electrolyte. The Zn content initially increases to a maximum by increase in off-time between pulses and then falls off. Adding a certain amount of Zn to Co led to form amorphous CoZn nanowires. A significant increase in magnetization, coercivity and squareness of CoZn nanowires was observed after annealing. The rate of increase in magnetization of annealed samples was seen to be inversely proportional to their initial magnetization. Improvement of magnetic properties of annealed samples may be caused by magnetic cluster formation and pinning effect. (C) 2012 Elsevier B.V. All rights reserved.
