By first-principles calculations, we present a doping-dependent phase diagram of LaO{\it M}As ({\it M}=V--Cu) family. It is characterized as antiferromagnetic semiconductor around LaOMnAs side and...

We have measured the normal state temperature dependence of the Hall effect and magnetoresistance in epitaxial MgB2 thin films with variable disorders characterized by the residual resistance ratio...

To justify the origin of anomalous Hall effect (AHE), it is highly desirable to have the system parameters tuned continuously. By quantitative calculations, we show that the doping dependent sign...
Spin-orbit gap of graphene: First-principles calculations (2006)
Yao, Yugui, Ye, Fei, Qi, Xiao-Liang, Zhang, Shou-Cheng, Fang, Zhong
Even though graphene is a low energy system consisting of the two dimensional honeycomb lattice of carbon atoms, its quasi-particle excitations are fully described by the 2+1 dimensional relativistic...
Linear magnetization dependence of the intrinsic anomalous Hall effect (2006)
Zeng, Changgan, Yao, Yugui, Niu, Qian, Weitering, Hanno H.
The anomalous Hall effect is investigated experimentally and theoretically for ferromagnetic thin films of Mn$_5$Ge$_3$. We have separated the intrinsic and extrinsic contributions to the...
Berry phase effect in anomalous thermoelectric transport (2006)
Xiao, Di, Yao, Yugui, Fang, Zhong, Niu, Qian
We develop a theory of Berry phase effect in anomalous transport in ferromagnets driven by statistical forces such as the gradient of temperature or chemical potential. Here a charge Hall current...
Ab initio calculation of intrinsic spin Hall effect in semiconductors (2005)
Guo, G. Y., Yao, Yugui, Niu, Qian
Relativistic band theoretical calculations reveal that intrinsic spin Hall conductivity in hole-doped archetypical semiconductors Ge, GaAs and AlAs is large $[\sim 100 (\hbar/e)(\Omega cm)^{-1}]$,...
Coherent wave-packet evolution in coupled bands (2004)
Culcer, Dimitrie, Yao, Yugui, Niu, Qian
We develop a formalism for treating coherent wave-packet dynamics of charge and spin carriers in degenerate and nearly degenerate bands. We consider the two-band case carefully in view of spintronics...
Electric generation of spin in crystals with reduced symmetry (2004)
Culcer, Dimitrie, Yao, Yugui, MacDonald, Allan, Niu, Qian
We propose a simple way of evaluating the bulk spin generation of an arbitrary crystal with a known band structure in the strong spin-orbit coupling limit. We show that, in the presence of an...
First Principles Calculation of Anomalous Hall Conductivity in Ferromagnetic bcc Fe (2003)
Yao, Yugui, Kleinman, L., MacDonald, A. H., Sinova, Jairo, Jungwirth, T., Wang, Ding-sheng, ...
We perform a first principles calculation of the anomalous Hall effect in ferromagnetic bcc Fe. Our theory identifies an intrinsic contribution to the anomalous Hall conductivity and relates it to...
