我们报道了在氧化硅衬底上生长的超薄FePt （1-10nm）薄膜的微观结构和磁性能的研究，其中有10nm的MgO（100）中间层。制备出了具有高L10有序度和大磁晶各向异性的FePt颗粒，其厚度小于5nm。分离FePt粒子的垂直矫顽力在15 ~ 25kOe之间可控。这些结果对于磁记录应用来说是很有希望和非常理想的。
We report the investigation of microstructure and magnetic properties of ultrathin FePt (1–10nm) films grown on oxidized Si substrates with a 10nm MgO(100) intermediate layer. The isolated FePt particles with high degree of L10 ordering and large magnetocrystalline anisotropy could be fabricated with a thickness of less than 5nm. Perpendicular coercivity of isolated FePt particles is controllable between 15 and 25kOe. These results are promising and highly desirable for magnetic recording applications.
