CrO2: A Self-Doped Double Exchange Ferromagnet

With the help of band structure calculations $(\mathrm{LSDA}+U)$ a clear picture of the physics behind the metallic ferromagnetic properties of ${\mathrm{CrO}}_{2}$ is revealed. It is concluded that ${\mathrm{CrO}}_{2}$ is a negative charge transfer gap material which leads to self-doping and explai... View More
