چکیده

The problem of importance of strong correlations for the electronic structure, transport, and magnetic properties of half-metallic ferromagnetic CrO2 is addressed by performing density functional electronic structure calculations in the local spin density approximation sLSDAd as well as using the LSDA1U method. It is shown that the corresponding low-temperature experimental data are best fitted without accounting for the Hubbard U corrections. We conclude that the ordered phase of CrO2 is weakly correlated.

Domain structures and the influence of current on domains and domain walls in highly spin-polarized CrO2 wire elements

We present a detailed study of the equilibrium magnetization configurations and their response to injected current pulses in microstructured CrO2 wire elements. Using magnetic force microscopy, we determine that the magnetic domain structure of CrO2 wires strongly depends on the wire geometry, in particular, on the wire width and the wire orientation with respect to the magnetocrystalline aniso...

Magnetic anisotropy of textured CrO2 thin films investigated by X-ray magnetic circular dichroism

Highly a-axis-textured CrO2 films have been deposited on Al2O3 (0001) substrates by chemical vapor deposition. CrO2 has been found to have highly a-axis (010)-oriented columnar growth on a Cr2O3 (0001) initial layer. The sixfold surface symmetry of the Cr2O3 initial layer leads to three equivalent in-plane orientations of the a-axis-oriented CrO2 unit cell. We report Cr L2,3 X-ray magnetic circ...

Strong anisotropy of projected 3d moments in epitaxial CrO2 films.

Soft x-ray magnetic circular dichroism (XMCD) spectra have been investigated for different crystallographic projections of CrO2. Strong anisotropic orbital Cr 3d contributions and a change of sign of the XMCD signal is observed and attributed to t(2g) majority states near the Fermi level. Additionally, moment analysis exhibits anisotropic behavior in the projected spin contributions of CrO2 ass...

Probing magnetic anisotropy effects in epitaxial CrO2 thin films

The magnetic anisotropy in ferromagnetic chromium dioxide thin films (Tc;393 K) grown epitaxially on ~100! TiO2 substrates, is probed using precise rf transverse susceptibility (xT) measurements. Singular peaks in xT are observed that are associated with the anisotropy (6HK) and switching (6Hs) fields in CrO2. Theoretical calculations of xT based on a simple coherent rotation model display rema...

Electronic and magnetic properties of SnO2/CrO2 thin superlattices

In this article, using first-principles electronic structure calculations within the spin density functional theory, alternated magnetic and non-magnetic layers of rutile-CrO2 and rutile-SnO2 respectively, in a (CrO2)n(SnO2)n superlattice (SL) configuration, with n being the number of monolayers which are considered equal to 1, 2, ..., 10 are studied. A half-metallic behavior is observed for th...
