MOSSBAUER EFFECT SPECTRA OF PbFe₁₂O₁₉ SINGLE CRYSTAL

【摘要】 <正> Ⅰ. INTRODUCTIONSince 1966 a number of successful experiments have been made on the study of Mssbauer effect of M-type hexagonal ferrites, such as BaFe₁₂O₁₉ and SrFe₁₂O₁₉. As for the study results of Mssbauer effect of PbFe₁₂O₁₉ very little has been reported. Unlike BaFe₁₂O₁₉ and SrFe₁₂O₁₉, PbFe₁₂O₁₉ is not a technically important hardmagnetic material, but it is no less interesting to inquire microscopically into the different magnetic properties of them.更多还原
