  Abstract: Anisotropic magnetoresistance (AMR), whose physical origin is attributed to the combination of spin dependent scattering and spin orbital coupling (SOC), usually displays simple angular dependence for polycrystalline ferromagnetic metals. By including generic spin dependent scattering and spin Hall (SH) terms in the Ohm's law, we explicitly show that various magneto-transport phenomena such as anomalous Hall (AH), SH, planar Hall (PH) and AMR could be quantitatively related for bulk polycrystalline ferromagnetic metals. We also discuss how AMR angular dependence is affected by the presence of interfacial SOC in magnetic layered structure. © 2014 AIP Publishing LLC.

  Abstract: In the literature there are two s-d models (by De Angeli et al. and by Zhang and Zhang) on the dynamics of noncollinear magnetization which treat the spin current density in completely different ways. It is shown that both models yield similar results for the spatial dependence of the damping term in such systems. The interrelations between the two models are discussed extensively. © 2012 Elsevier B.V.

  Abstract: Magnetization dynamics at high temperatures involves both transverse and longitudinal relaxation. The recently formulated Landau-Lifshitz-Bloch and self-consistent Bloch equations are capable of addressing some essential features of magnetization dynamics near Curie temperatures. Here, we analyze these two effective equations in detail and compare their dynamic properties near the Curie temperature. © 2013 AIP Publishing LLC.

  Exchange interaction between conduction electrons and magnetic moments at magnetic interfaces leads to mutual conversion between spin current and magnon current. We introduce a concept of spin convertance which quantitatively measures magnon current induced by spin accumulation and spin current created by magnon accumulation at a magnetic interface. We predict several phenomena on charge and spin drag across a magnetic insulator spacer for a few layered structures. DOI: 10.1103/PhysRevB.86.214424

  Abstract: We present a model for determining the Rashba spin-orbit coupling (RSOC) at magnetic surfaces or interfaces by explicitly taking into account the interaction between the inversion-symmetry-broken potential and the spin-dependent electric dipoles of the Bloch states. We show that the RSOC alone can generate a perpendicular surface magnetic anisotropy comparable to the observed values in transition metals. When an external electric field is applied across the interface, the induced screening potential modifies the RSOC and thus controls the direction of the magnetization. Our results are consistent with the existing experiments. © 2012 American Institute of Physics.

  Abstract: By using the quantum kinetic approach with the instantaneous local equilibrium approximation, we propose an equation that is capable of addressing magnetization dynamics for a wide range of temperatures. The equation reduces to the Landau-Lifshitz equation at low temperatures and to the paramagnetic Bloch equation at high temperatures. We further include the stochastic fields in the dynamic equation in order to take into account fluctuation at high temperatures. Our proposed equation overcomes the non-analytic damping coefficients in the Landau-Lifshitz-Bloch (known as LLB) equation and can be broadly used for modeling laser pump-probe experiments and heat assisted magnetic recording. © 2012 Elsevier B.V.

  More info

  Abstract: Laser-induced demagnetization is theoretically studied by explicitly taking into account interactions among electrons, spins, and lattice. Assuming that the demagnetization processes take place during the thermalization of the subsystems, the temperature dynamics is given by the energy transfer between the thermalized interacting baths. These energy transfers are accounted for explicitly through electron-magnon and electron-phonon interactions, which govern the demagnetization time scale. By properly treating the spin system in a self-consistent random phase approximation, we derive magnetization dynamic equations for a broad range of temperature. The dependence of demagnetization on the temperature and pumping laser intensity is calculated in detail. In particular, we show several salient features for understanding magnetization dynamics near the Curie temperature. While the critical slowdown in dynamics occurs, we find that an external magnetic field can restore the fast dynamics. We discuss the implication of the fast dynamics in the application of heat-assisted magnetic recording. © 2012 American Physical Society.

  Abstract: In a semiconductor heterostructure, the Coulomb interaction is responsible for the electric current drag between two 2D electron gases across an electron impenetrable insulator. For two metallic layers separated by a ferromagnetic insulator (FI) layer, the electric current drag can be mediated by a nonequilibrium magnon current of the FI. We determine the drag current by using the semiclassical Boltzmann approach with proper boundary conditions of electrons and magnons at the metal-FI interface. © 2012 American Physical Society.
