  • Detected anomalies in dispersion and momentum broadening near the Fermi level.
  • Identified an energy scale for bosonic excitations significantly larger than phonons and matching the spin wave spectrum.

    • Conclusions:

    • Spectroscopic evidence confirms quasiparticle mass enhancement due to electron-magnon coupling.
    • The findings highlight the significant role of spin waves in renormalizing electronic properties of iron.
