  Abstract The (Fe x Co 1−x ) 3 B (x = 0.0, 0.1, 0.2, 0.3) compounds have been prepared by induction melting with subsequent annealing. All of the compounds form in the orthorhombic Fe 3 C-type structure and exhibit ferromagnetic behaviour: the Curie temperature increases from 750 K for x = 0.0 to 923 K for x = 0.3. Magnetic domain images obtained by Kerr microscopy reveal the presence of uniaxial magnetocrystalline

  The Oxygen evolution reaction on cobalt borides and composite cobalt borides was investigated in a 6M KOH solution (1 M=1 mol dm−3) using the factor of the magnetic properties. In the system of cobalt borides (Co:B=3:1) prepared at various sintering temperatures, the boride having a higher saturation magnetization revealed a higher activity of the oxygen evolution reaction. In the system of composite cobalt borides which have various magnetic moments, μB, a clear correlation between the activity of the oxygen evolution reaction and the saturation magnetization (or magnetic moment, μB) was observed for several composite cobalt boride species (i.e., Co–Fe–B, Co–Ni–B, Co–Mn–B, and Co–B). Among the composite cobalt boride species, the cobalt iron boride (Co:Fe:B=1:2:1) sintered at 450 °C showed the highest activity of oxygen evolution reaction in a 6 M KOH solution. The conditions of oxide formation on Co–Fe–B(1:2:1) and on Co–B(3:1) in a 6 M KOH solution were compared with those on cobalt by means of voltammetry and chronopotentiometry. It was concluded that the ease and stability of oxide films in higher oxidation states are strongly correlated to the activity of the oxygen evolution reaction which occurs on more highly oxidized oxide films.

  在6M KOH溶液（1 M=1 mol dm−3）中，利用磁性质因子研究了钴硼化物和复合钴硼化物中的氧析出反应。在各种烧结温度下制备的钴硼化物（Co:B=3:1）体系中，具有更高饱和磁化的硼化物显示出更高的氧析出反应活性。在具有不同磁矩μB的复合钴硼化物体系中，观察到几种复合钴硼化物（即Co–Fe–B、Co–Ni–B、Co–Mn–B和Co–B）的氧析出反应活性与饱和磁化强度（或磁矩μB）之间存在明显的相关性。在复合钴硼化物中，在450 °C下烧结的钴铁硼化物（Co:Fe:B=1:2:1）在6 M KOH溶液中显示出最高的氧析出反应活性。通过伏安法和恒电位法，将6 M KOH溶液中Co–Fe–B(1:2:1)和Co–B(3:1)的氧化物形成条件与钴的氧化物形成条件进行了比较。结果表明，高氧化态下氧化物膜的易形成性和稳定性与氧析出反应

  AN investigation by X-ray powder methods of the nickel–boron and the cobalt–boron systems has revealed the existence of two isomorphous borides, Ni3B and Co3B. A nickel boride with a boron content about 25 atom per cent has previously been reported by Andersson and Kiessling1, but no reports on Co3B seem to have been published.

  通过X射线粉末法对镍硼和钴硼系统进行的调查表明，存在两种同素异形体硼化物，即Ni3B和Co3B。此前，Andersson和Kiessling1曾报道过一种硼含量约为25%的镍硼化物，但似乎没有关于Co3B的报道。

  Abstract We present an XPS and UPS study of crystalline Co, Co 3 B and Co 78 P 14 B 8 glassy metal. For Co 3 B the electronic distribution curves (EDC) of the valence band and the previous specific heat and magnetic results are interpreted in a qualitative model where : i) the s-p cobalt-boron bonding states lie in the low part of the band, the upper levels being mainly cobalt d states and ii) a large

  摘要 我们介绍了晶体 Co、Co 3 B 和 Co 78 P 14 B 8 玻璃态金属的 XPS 和 UPS 研究。对于 Co 3 B，价带的电子分布曲线 (EDC) 和先前的比热和磁结果在定性模型中解释，其中： i) sp 钴-硼键合状态位于带的低部，上能级主要是钴 d 态和 ii) 大部分自旋带的大密度态存在于费米能级。对于非晶 Co 78 P 14 B 8 ，EDC 显示 EF 位于高态密度区域，建议磷 p 态 ae 集中在 7.5 eV。光电发射和磁性结果也可以在先前模型的框架中进行解释。
