Özet
Chromium dioxide (CrO2) has attracted specific interest as a compound possessing near 100% spin polarization at the Fermi level. Its half-metallic performance leads to relatively low electrical resistivity for an oxide. It is also ferromagnetic at room temperature relative to the other half-metal candidates. These properties and wide availability of CrO2 make this material technologically and scientifically noteworthy and a perfect substance for developing spintronic devices [1–11]. This material is regarded as a perfect candidate for enhancing spintronic devices, tunneling magnetoresistance devices, magnetic heads, magnetic random access memories, and magnetic field sensors. Due to the uniaxial crystal structure, CrO2 is estimated to have a great magnetic anisotropy which makes it a preferable material for magneto-optical recording [3, 12–21]. CrO2 crystallizes in a tetragonal rutile-type structure with space group P42/mnm at ambient conditions like TiO2, MnO2, RuO2, SnO2, GeO2, etc. Among these rutile-type dioxides, CrO2 has exceptional meaning because CrO2 is the only half-metallic ferromagnet. A phase transformation from the tetragonal rutiletype to the CaCl2-type structure is observed by Maddox et al.[12] at 12±3 GPa.
