Abstract
Spin-resolved photoemission from polycrystalline Cr films shows a spin polarization () of nearly +100% for binding energies near 2 eV below the Fermi level (). Despite the metallic resistivity behavior, extremely low intensity is observed in the photoemission spectra near . Our findings are in contrast to recent band-structure calculations, predicting Cr to be a half-metallic ferromagnet with at .
