摘要： The present invention provides for polycrystalline superconducting permanent magnets which are synthesized of doped superconducting (AE) Fe2As2 compounds, where AE denotes an alkaline earth metal, such as Ba, Sr, Mg or Ca. The superconducting permanent magnets of the present invention can be magnetized in their superconducting state by induced currents, resulting in trapped magnetization that scales with the size of the bulk material. The magnitude of the trapped field has been demonstrated to be over 1 T and is predicted to be over 10 T if the technology is scaled, which is much higher than the capabilities of permanent magnets and other superconducting polycrystalline bulks currently known in the art.

摘要： Permanent magnets are used for several important applications, including de electrical motors, wind turbines, hybrid automobile, and for many other applications. Modern widely used rare-earth based permanent magnet materials, such as Sm—Co and Nd—Fe—B, are generally intermetallic alloys made from rare earth elements and transition metals such as cobalt. However, the high costs of rare earth elements make the widespread use of these permanent magnets commercially unattractive. The present work focuses on producing a new permanent magnet material, with good magnetic properties, which is free from rare-earth elements and thus cost-effective. The present invention provides a process to synthesis boron doped manganese antimonide as an alternative to rare earth based permanent magnet materials. The boron doped manganese antimonide disclosed in this invention is free from rare-earth element with good magnetic properties. The material in the present study has been synthesized employing sequential combination of high energy ball milling, arc melting under argon atmosphere and again high energy ball milling followed by annealing. The annealed boron doped manganese antimonide shows improved magnetic properties as compared to manganese antimonide.
摘要翻译：永磁体用于几个重要的应用，包括电机，风力发电机，混合动力汽车以及许多其它应用。现代广泛使用的稀土类永磁材料如Sm-Co和Nd-Fe-B通常是由稀土元素和过渡金属如钴制成的金属间合金。然而，稀土元素的高成本使得这些永磁体的广泛使用在商业上没有吸引力。目前的工作重点是生产一种具有良好磁性能的新型永磁材料，其不含稀土元素，因此具有成本效益。本发明提供了一种合成硼掺杂的锑化锰作为稀土类永磁材料的替代方法。本发明公开的硼掺杂锑化锑不含具有良好磁性能的稀土元素。本研究中的材料是采用高能球磨，氩气气氛电弧熔炼和再次高能球磨随后退火的顺序组合而合成的。退火的硼掺杂的锰锑与锑化锑相比显示出改进的磁性能。
