中文摘要In this paper, the remanence properties of Co-Sn, Co-Ti and CO-Ti-Sn substituted Ba-ferrite (BaF) oriented particulate samples are compared with those of some oriented acicular particulate samples. A new parameter, the minor remanence distribution (MRD), is proposed to review the remanence properties of magnetic particles and the capabilities for resisting the recording demagnetization of magnetic recording media. It is shown that the MRD values of the oriented BaF particulate samples were smaller compared to oriented Co-gamma-Fe2O3 samples, even though the squareness ratios (SR) of some of the BaF samples were smaller than those of the Co-gamma-Fe2O3 samples. It is the small MRD, SFD(r), IRS and large DH(r) of a medium that can result in a large resistance to the effects of recording demagnetization and therefore in superior characteristics for high density magnetic recording. Since Co-Sn substituted BaF platelet-shaped particles exhibit these characteristics and have a very low temperature coefficient of coercivity, these particles can be expected to be a promising candidate for high density magnetic recording.
