Evidence for two-band magnetotransport in half-metallic chromium dioxide
TL;DR: Magnetotransport measurements were made on patterned, (110) oriented, thin films grown by the high-pressure, thermal decomposition of ${\mathrm{CrO}}_{3}$ onto rutile substrates as mentioned in this paper.
A CrO2-based magnetic tunnel junction
TL;DR: A tunnel junction based on the half-metallic oxide CrO2 using a native oxide barrier layer and a cobalt top electrode is described in this article, where the I :V characteristic is fitted to the Simmons model with = 0.76 eV and t = 2.0 nm.

Charge dynamics in the half-metallic ferromagnet CrO 2
TL;DR: In this paper, the authors used infrared spectroscopy to investigate the electronic structure and charge carrier relaxation in crystalline films of half-metallic ferromagnetic oxides and showed that low residual resistivity is due to the collapse of the scattering rate.
Raman spectra of the half-metallic ferromagnet cro2
TL;DR: In this paper, the polarized Raman spectra of CrO2 between 5 and 420 K were obtained from (110) and (001) oriented thin films on TiO2 substrates of the same orientation.

Evidence for a gap in the excitation spectrum of CrO2
TL;DR: In this article, magnetization and resistivity of oriented CrO2 films on different TiO2 single-crystal substrates are reported, and the low-temperature specific heat is measured on powders.
