Abstract

Scanning electron microscopy, atomic force microscopy, X-ray spectral microanalysis, and measurements of magnetic characteristics were used to analyze the local properties and several possibilities for modifying the near-surface layers of Fe₇₃(SiBNb)₂₇ amorphous ribbon electrical material, the same material with the addition of 1% copper, and the promising rare-earth-free hard magnetic material (Fe₆₅Co₃₅)₂B. The materials were produced by melt spinning through ultrarapid cooling by spraying the melt onto a rapidly rotating copper drum. The surface of the (Fe₆₅Co₃₅)₂B samples was found to have a pronounced fan-shaped texture. Several possibilities for modifying the near-surface layers of the Fe₇₃(SiBNb)₂₇ amorphous alloy with the addition of 1% copper by exposure to weak magnetic-field pulses were studied. Magnetic pulse treatment was found to produce a domain structure on the free surface of the foil (the surface not in contact with the drum). The nature of the domain structure and the magnetic properties of the foil depend on the parameters of magnetic pulse treatment.

熔体纺丝制备Fe73(SiBNb)27和（Fe65Co35）2B带状电材料的局部性能分析及近表面改性的可能性

利用扫描电子显微镜、原子力显微镜、x射线光谱显微分析和磁特性测量分析了Fe73(SiBNb)27非晶带状电材料、添加1%铜的相同材料和有前途的无稀土硬磁材料（Fe65Co35）2B近表面改性的局部性质和几种可能性。该材料是通过将熔体喷射到快速旋转的铜鼓上，通过超快速冷却进行熔体纺丝生产的。发现（Fe65Co35）2B样品的表面具有明显的扇形纹理。研究了在弱磁场脉冲作用下添加1%铜修饰Fe73(SiBNb)27非晶态合金近表层的几种可能性。发现磁脉冲处理在箔的自由表面（不与鼓接触的表面）上产生域结构。磁脉冲处理的参数决定了箔的畴结构性质和磁性能。

期刊介绍： Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
