论文摘要
据报道，在5个开尔文和300 kelvin之间的温度以及70千欧 - 奥斯特的磁场上，磁性，比热和结构特性据报道。在铸造，退火和冷工作的样品上进行的磁化测量结果显示出强大的处理历史依赖性，并且冷工作后的高温退火不会使合金恢复到原始状态。对已知沉淀物的测量表明，在43开尔文和85 kelvin处检测到的两个过渡是cantor合金固有的，而不是杂质阶段的结果。实验和抗启动密度功能理论（DFT）的计算结果表明，这些转变分别是弱铁磁过渡和旋转玻璃的跃迁，并且磁性和特定的热量测量值提供了明显的Stoner增强和电子电子相互作用的证据。
Magnetic, specific heat, and structural properties of the equiatomic Cantor alloy system are reported for temperatures between 5 kelvin and 300 kelvin, and up to fields of 70 kilo-oersted. Magnetization measurements performed on as-cast, annealed, and cold-worked samples reveal a strong processing history dependence and that high-temperature annealing after cold-working does not restore the alloy to a pristine state. Measurements on known precipitates show that the two transitions, detected at 43 kelvin and 85 kelvin, are intrinsic to the Cantor alloy and not the result of an impurity phase. Experimental and ab initio density functional theory (DFT) computational results suggest that these transitions are a weak ferrimagnetic transition and a spin-glass-like transition, respectively, and magnetic and specific heat measurements provide evidence of significant Stoner enhancement and electron-electron interactions within the material.
