Spectroscopic Evidence for Electron-Boson Coupling in Half-metallic CrO2

Daiki Ootsuki, Hirokazu Fujiwara, Noriyuki Kataoka +9

We report quasiparticle properties of the half-metal ferromagnet CrO2 by means of high-resolution angle-resolved photoemission spectroscopy (ARPES). We clearly observed the Fermi s…
