Abstract

We have examined the intrinsic surface physical property of a CrO ₂ thin film by means of surface sensitive photoemission spectroscopy. Epitaxial thin film of CrO ₂(100) has been grown on TiO ₂(100) by a closed chemical vapor deposition method using a Cr ₈O ₂₁ precursor. Low-energy electron diffraction (LEED) observations find that epitaxial growth of rutile-phase CrO ₂ occurs to the top monolayer of the film. Surface sensitive x-ray photoemission spectroscopy (XPS) measurements show a finite intensity in the region of the Fermi energy. The result evidences that the physical nature of near topmost layer of CrO ₂ thin film is metallic. Progress of understanding of the surface physical property of CrO ₂ thin film helps not only perform a reliable photoemission study to understand the physics of ferromagnetic metal in CrO ₂, but also develop the CrO ₂-based devices using a half-metallic nature for spintronics applications.
