论文摘要
摘要提出了曲线类型的软磁性非晶合金的强脉冲离子束(IPIB)的结果。用合金产生的箔被短(约100 ns)的碳离子和质子的纯液和能量高达300 keV,能量密度高达7 j/cm2。 X射线衍射,Mössbauer光谱和磁性测量用于研究辐照箔的结构和磁性。结果表明,处理后箔保持完整,并且晶体结构仍然无定形。发现自发磁化载体几乎沿辐照后垂直于箔平面,而对于初始的无定形箔,它属于平面。箔的磁性发生变化:强制性减少,饱和感略微增加,并且磁化曲线具有较浅的斜率。
Abstract The results of intense pulsed ion beam (IPIB) treatment of the soft magnetic amorphous alloy of a FINEMET-type are presented. Foil produced from the alloy was irradiated with short (about 100 ns) pulses of carbon ions and protons with energy of up to 300 keV and an energy density of up to 7 J/cm2. X-ray diffraction, Mössbauer spectroscopy and magnetic measurements were used to investigate structural and magnetic properties of irradiated foils. It is shown that the foil remains intact after the treatment, and the crystal structure still amorphous. Spontaneous magnetization vector is found to lie almost along perpendicular to the foil plane after irradiation, whereas for the initial amorphous foil it belongs to the plane. The magnetic properties of the foil undergo changes: the coercive force decreases, the saturation induction increases slightly, and the magnetization curve has shallower slope.
