一、引言自从1966年以来,对M型六角铁氧体,例如BaFe_(12)O_(19)与SrFe_(12)O_(19)等,进行了一系列的穆斯堡尔谱学研究,以确定这类材料的微观磁化机制。但是,关于PbFe_(12)O_(19)的穆斯堡尔谱的研究结果却报道不多。虽然PbFe_(12)O_(19)不像BaFe_(12)O_(19)与StFe_(12)O_(19)那样是一种有实际应用价
I. Introduction Since 1966, a series of Mössbauer spectroscopic studies have been carried out on M-type hexagonal ferrites, such as BaFe 12 O 19 and SrFe 12 O 19. Determine the micro-magnetization mechanism for this type of material. However, there are few reports about the Mossbauer spectra of PbFe_ (12) O_ (19). Although PbFe_ (12) O_ (19) is not as practical as BaFe_ (12) O_ (19) and StFe_ (12) O_ (19)
