Abstract Current work is devoted to the study of magneto-optical properties of ferromagnetic metal-carbon nanocomposites that belong to a new class of composites in which partial mixing and the formation of metastable phases between components are allowed. Films of nanocomposites were obtained using ion-beam sputtering of composite target on ceramic substrates. There were three systems synthesized with wide range of magnetic phase concentrations – (Co 40 Fe 40 B 20 ) X (SiO 2 ) 100−X (1), (Co 401 Fe 40 B 20 ) X (C) 100−X (2)and (Co) X (C) 100−X (3). It is found that the evolution of the TKE spectra for the [(Co) x (C) 100−x ] system with a change in the concentration of FM granules indicates a transition from amorphous CoC granules to crystalline Co granules in a carbon matrix. The shape TKE spectra for the system2 was weakly dependent on the concentrations x. The difference in the behavior of the magneto-optical properties of the [(Co) x (C) 100−x ] and [(Co 40 Fe 40 B 20 ) x (C) 100−x ] system is explained on the basis of the composite formation model, taking into account the possibility of chemical reactions of carbon with metals and boron.

纳米复合铁磁碳的磁光特性

摘要 目前的工作致力于研究铁磁性金属-碳纳米复合材料的磁光特性，该复合材料属于一类新的复合材料，其中允许成分之间的部分混合和亚稳相的形成。使用离子束溅射在陶瓷基板上复合靶材获得纳米复合材料薄膜。合成了三种具有广泛磁性相浓度范围的系统 - (Co 40 Fe 40 B 20 ) X (SiO 2 ) 100-X (1), (Co 401 Fe 40 B 20 ) X (C) 100-X (2 ) 和 (Co) X (C) 100-X (3)。发现 [(Co) x (C) 100-x ] 系统的 TKE 光谱随 FM 颗粒浓度变化的演变表明碳基质中从无定形 CoC 颗粒到结晶 Co 颗粒的转变。系统 2 的形状 TKE 光谱与浓度 x 有微弱的关系。[(Co) x (C) 100-x ] 和 [(Co 40 Fe 40 B 20 ) x (C) 100-x ] 系统的磁光特性行为的差异基于以下解释：复合形成模型，考虑到碳与金属和硼发生化学反应的可能性。
