Enhanced Microwave Absorption Performance of Amorphous Co<sub>100-x</sub>Fe<sub>x</sub> Nanoparticles.

Based on the volume fractions and the corresponding M s values of pure Co and Fe [ 15 ], the calculated M s values for Co 70 Fe 30 , Co 50 Fe 50 , and Co 30 Fe 70 are 70, 100.9, and 131.8 emu/g, respectively, showing an increasing trend with Fe content, which is consistent with the experimental results presented in Figure 3 b.
