【摘要】 测量了M型,W型和X型六角钡铁氧体的Mossbauer谱,采用多组六线洛伦兹的叠加谱与实验谱逐步逼近的方法解出了M型和W型材料的Mossbauer谱参量。从结晶学构造出发,X型可以视为M型和W型的叠加,由此解得了十一组六线次谱,并对实验数据取得较好的拟合。更多还原

【Abstract】 The M(?)ssbauer spectra for the M-, W- and X-type hexagonal barium ferrites were measured. We obtained the M(?)ssbauer spectra parameters of the M- and W-type ferrites, using the method of trial and error of a number of superposed six-line Lorentzian spectra with experimental spectra. In crystallographic consideration the X-type ferrites may by regarded as a superposition of M- and W-type. Then we obtained eleven six-line sub-spectra of the X-type with good fitting of experimental data.更多还原
