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.展开更多
