我们利用穆斯堡尔谱从微观角度研究了“SiO2-纳米反应器”法合成的L10-FePt纳米颗粒的磁性能。几乎所有的纳米粒子都具有与大块 L10-FePt 合金几乎相同的穆斯堡尔超精细参数，这表明尽管它们的尺寸很小（6.5 nm），但它们具有与大块状态相当的明确的 L10 结构。
We investigated magnetic properties of the L10-FePt nanoparticles synthesized by the “SiO2-nanoreactor” method by means of Mössbauer spectroscopy from the microscopic point of view. Almost all of the nanoparticles were revealed to have nearly the same Mössbauer hyperfine parameters as those of the bulk L10-FePt alloy, indicating that they have well-defined L10 structure equivalent to the bulk state in spite of their small size of 6.5 nm.
