| Abstract: | Perpendicular magnetic recording （PMR） is the dominant method to storage information at present. How- ever, PMR has reached the areal density limit due to the low magnetocrystalline anisotropy of the current recording media CoCrPt. To further improve the density of PMR, it is necessary to use media with higher magnetocrystalline anisotropy. L10 FePt and CoPt are regarded as the most potential candidate of recording media for the next genera tion high-density magnetic recording. In this article, the study progress of L10 FePt and CoPt is reviewed. |
