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.

Effective Magnetic Anisotropy

The effective magnetic anisotropy of the ferromagnetic nanocrystalline Fe-Zr-N films prepared by magnetron sputtering under different conditions has been determined by both correlation magnetometry and ferromagnetic resonance methods. The effective magnetic anisotropy values obtained by the two methods are compared and the origin of the values is discussed.
