摘要 通过溶胶-凝胶法制备了L10相CoPt磁性纳米颗粒.结果表明,不同热处理过程对CoPt纳米颗粒的结构和磁性有着明显的影响.磁性测试结果显示,所制备的L10相CoPt纳米颗粒在室温下具有铁磁性. In this letter,we prepared ordered L10 CoPt magnetic nanoparticles.The results showed the different heat treatment process had evident effect on the structure and magnetic properties of CoPt nanoparticles.VSM results indicated prepared L10 CoPt nanoparticles was ferromagnetic at the room temperature.
