摘要：

In this study, we develop a novel urchin-like Co nanomatrixprecursorthat allows for precise control of the Sm/Pr ratio in the compositematerial, resulting in the successful synthesis of Sm x Pr1-x Co5 particles with tunable magnetic properties and strong anisotropy.Our analysis, including transmission electron microscopy and elementalmapping, confirmed the creation of single-crystal Sm x Pr1-x Co5 particleswith controllable composition and desired properties. Notably, theSm(0.5)Pr(0.5)Co(5) particles demonstratedsignificant magnetocrystalline anisotropy and exceptional magneticproperties, including a high (BH)(max) of 16.1 MGOe and ahigh H (cj) of 13.4 kOe. This innovativemethod may advance facile access to the chemical synthesis of multicomponentrare earth magnetic particles with adjustable properties to meet differentapplication requirements.
