摘要：

Structure tuning of FePt nanomagnets is achieved by using a gas-phase condensation technique (see figure). Three types of FePt nanomagnets, A1 phase icosahedron, A1 phase octahedron, and L10 phase octahedron, with uniform size distributions are produced by directly manipulating the thermal environments for the nucleation and growth. The different magnetic performances of these nanomagnets are consistent with their structure variances.
