Effect of Rare-Earth Doping on Dynamic Magnetic Properties of FeGa Alloy

“…4a and 5a) RE doped alloys have higher coercive field values than binary alloy. The reason is the hard magnetic properties of the RE-rich phase [13], reflected in higher quasi-static field 𝐻𝐻 𝑐𝑐 𝐷𝐷𝐷𝐷 , which is the main component at the given 𝐵𝐵 𝑚𝑚 and frequency range. Moreover, at 10 Hz, the contributions of the dynamic field are very low, thus 𝐻𝐻 𝑐𝑐 increases with RErich phase content (Fig.…”
