We report on the effect of Carbon insertion on the microstructure and magnetic properties of nanocrystalline Pr2Co7Cx([Formula: see text]). The Pr2Co7Cx were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and physical property measurement system (PPMS9) Quantum Design. Mean field theory was utilized to depict the temperature dependence of magnetization and deduce the exchange interactions. The approach to saturation magnetization was as well used. The results were interpreted in the framework of random magnetic anisotropy model. From such analysis, some fundamental parameters were extracted.

纳米晶 Pr2Co7Cx(x≤1) 中的磁饱和趋近定律：碳化的影响

我们报告了碳插入对纳米晶镨微观结构和磁性的影响2公司7CX（[公式：见正文]）。公关2公司7CX通过 X 射线衍射 (XRD)、透射电子显微镜 (TEM) 和物理性质测量系统 (PPMS9) 量子设计对其进行了表征。平均场理论用于描述磁化的温度依赖性并推断交换相互作用。饱和磁化的方法也被使用。在随机磁各向异性模型的框架下解释了结果。从这样的分析中，提取了一些基本参数。
