Epitaxial CrO 2 (100)-oriented film was successfully fabricated on TiO 2 (100) substrate by a simple chemical vapor deposition in a two-zone furnace with oxygen flow from a CrO 3 precursor. The transport measurements show that the CrO 2 film is metallic with a small residual resistivity 4 μΩ cm down to 0.6 K. The temperature dependence of resistivity was best described by a phenomenological expression ρ(T) = ρ0 + AT2 exp (-Δ/T) over the range of 0.6–300 K with Δ = 123.6 K. The magnetization of the film becomes saturated in a relatively low field with a small coercive field. The temperature dependence of magnetization shows Bloch's T3/2 law and the slope of the curve suggests a critical wavelength of λΔ ~ 26.6 Å beyond which spin-flip scattering becomes important.
