SiC中缺陷诱导铁磁性的解纠缠
Disentangling defect-induced ferromagnetism in SiC
摘要：
我们提出了一个详细的调查与氖离子轰击SiC单晶的磁性。通过仔细测量原始和辐照SiC的磁化强度，我们将SiC的磁化强度分解为顺磁、超顺磁和铁磁贡献。铁磁性的贡献仍然远高于室温，并表现出明显的磁各向异性。我们定性地解释了作为一个内在的缺陷的聚集倾向的结果的磁性。
英文摘要：
We present a detailed investigation of the magnetic properties in SiC single crystals bombarded with neon ions. Through careful measuring of the magnetization of virgin and irradiated SiC, we decompose the magnetization of SiC into paramagnetic, superparamagnetic, and ferromagnetic contributions. The ferromagnetic contribution persists well above room temperature and exhibits a pronounced magnetic anisotropy. We qualitatively explain the magnetic properties as a result of the intrinsic clustering tendency of defects.
