利用Taylor-Ulitovsky技术制备了Fe-Pt和Fe-Pt-(B, Si)微线，并研究了它们的磁性能。磁性能在很大程度上取决于金属芯的组成。微丝在制备状态下存在面心立方FePt3 （A1）无序相，呈现出非晶或非晶与纳米晶的混合相。我们得到了矫顽力在4 ~ 140 Oe之间的微丝，这可以从不同的金属核组织来解释。
We have prepared Fe-Pt and Fe-Pt-(B, Si) microwires using the Taylor-Ulitovsky technique and studied their magnetic properties. Magnetic properties considerably depend on the metallic core composition. Microwires present either amorphous or a mixture of amorphous and nanocrystalline phases with a presence of face-centered cubic FePt3 (A1) disordered phase in the as-prepared state. We obtained microwires with coercivities from 4 to 140 Oe, which can be explained considering different metallic nucleus microstructures.
