CrO2€A new half-metallic ferromagnet?

View publication

Abstract

Spin-resolved photoemission from polycrystalline CrO2 films shows a spin polarization (P) of nearly +100% for binding energies near 2 eV below the Fermi level (EF). Despite the metallic resistivity behavior, extremely low intensity is observed in the photoemission spectra near EF. Our findings are in contrast to recent band-structure calculations, predicting CrO2 to be a half-metallic ferromagnet with P=+100% at EF. © 1987 The American Physical Society.
