Title: Structural and magnetic properties of the CeCo 5–CeZn 5 solid solution and potential improvements upon iron substitution

Abstract

In an effort to create high-performance permanent magnets with reduced critical rare earth content, we explored the CeCo 5-xT x (T = transition metal or metalloid) family of compounds to investigate the effect of substitution on the material’s magnetic properties. In our exploration of the CeCo 5-xZn x system, we discovered a continuous solid solution at 900 °C between the CeCo 5 and CeZn 5 binary phases with ferromagnetism existing from the CeCo 5 compound to the intermediate CeCo 2.75Zn 2.25 compound. Single crystal studies were also conducted revealing a relatively large anisotropy field of 11.5 T at 300 K for Ce 0.96Ta 0.04Co 4.35Zn 0.65. Here, the addition of iron Ce 0.79Ta 0.07Co 3.77Fe 0.89Zn 0.47 yielded further increases in Curie temperature and saturation magnetization to 800 K and 85.5 emu/g, respectively.
