Co9Zn9Mn2手性磁体晶体生长与磁学性质研究
|
Abstract:
手性磁体Co-Zn-Mn体系因其高居里温度为拓扑磁性粒子的室温应用带来了希望。目前Co-Zn-Mn体系研究中的材料主要依赖助熔剂方法生长制备，获得的样品尺寸相对较小。实现较大尺寸样品的制备对Co-Zn-Mn体系室温拓扑磁性的系统性研究和技术应用有重要意义。本研究以Co9Zn9Mn2成分为研究对象，通过改善自助熔剂法实现了5 g规格Co9Zn9Mn2晶体的生长，并系统研究了其磁学性质。
The chiral Co-Zn-Mn alloy system has emerged as a promising candidate for room-temperature topological magnetic particles, owing to its elevated Curie temperatures. Samples currently used in research on the Co-Zn-Mn system are primarily grown and prepared using the flux method, resulting in samples of relatively small size. The preparation of relatively large-sized samples is crucial for systematic research and technological applications of room-temperature topological magnetism in the Co-Zn-Mn system. This study focuses on the composition of Co9Zn9Mn2 and achieves the growth of 5-gram scale Co9Zn9Mn2 crystals using a refined self-flux method and systematically investigated their magnetic properties.
