Clarke, D. J., Tretiakov, O. A., Bazaliy, Ya. B., Tchernyshyov, O.
The motion of a vortex domain wall in a ferromagnetic strip of submicron width under the influence of an external magnetic field exhibits three distinct dynamical regimes. In a viscous regime at low...
Slonczewski windmill with dissipation and asymmetry (2007)
J. Slonczewski invented spin-transfer effect in layered systems in 1996. Among his first predictions was the regime of ``windmill motion'' of a perfectly symmetric spin valve where the magnetizations...
Generation of microwave radiation in planar spin-transfer devices (2007)
Current induced precession states in spin-transfer devices are studied in the case of large easy plane anisotropy (present in most experimental setups). It is shown that the effective one-dimensional...
Dynamics of domain walls in magnetic nanostrips (2007)
Tretiakov, O. A., Clarke, D., Chern, Gia-Wei, Bazaliy, Ya. B., Tchernyshyov, O.
We express dynamics of domain walls in ferromagnetic nanowires in terms of collective coordinates generalizing Thiele's steady-state results. For weak external perturbations the dynamics is dominated...
Planar spin-transfer device with a dynamic polarizer (2007)
Bazaliy, Ya. B., Olaosebikan, D., Jones, B. A.
In planar nano-magnetic devices magnetization direction is kept close to a given plane by the large easy-plane magnetic anisotropy, for example by the shape anisotropy in a thin film. In this case...
Effective attraction induced by repulsive interaction in a spin-transfer system (2007)
In magnetic systems with dominating easy-plane anisotropy the magnetization can be described by an effective one dimensional equation for the in-plane angle. Re-deriving this equation in the presence...
Extremal transmission at the Dirac point of a photonic band structure (2007)
Sepkhanov, R. A., Bazaliy, Ya. B., Beenakker, C. W. J.
We calculate the effect of a Dirac point (a conical singularity in the band structure) on the transmission of monochromatic radiation through a photonic crystal. The transmission as a function of...
Bazaliy, Ya. B., Bazaliy, B. V., Guntherodt, G., Parkin, S. S. P.
Recently a new propagating mode of coupled charge and spin oscillations was predicted in a two dimensional electron gas with a sufficiently strong Rashba interaction. We show that Coulomb...
Spin-reorientation in YbFeO_3 (2005)
Bazaliy, Ya. B., Tsymbal, L. T., Kakazei, G. N., Kamenev, V. I., Wigen, P. E.
Precise measurements of YbFeO_3 magnetization in the spin-reoirentation temperature interval are performed. It is shown that ytterbium orthoferrite is well described by a recently developed modified...
Magnetotransport near a quantum critical point in a simple metal (2003)
Bazaliy, Ya. B., Ramazashvili, R., Si, Q., Norman, M. R.
We use geometric considerations to study transport properties, such as the conductivity and Hall coefficient, near the onset of a nesting-driven spin density wave in a simple metal. In particular,...
Hall Effect in Nested Antiferromagnets Near the Quantum Critical Point (2002)
Norman, M. R., Si, Qimiao, Bazaliy, Ya. B., Ramazashvili, R.
We investigate the behavior of the Hall coefficient in the case of antiferromagnetism driven by Fermi surface nesting, and find that the Hall coefficient should abruptly increase with the onset of...
Current Induced Magnetization Switching in Small Domains of Different Anisotropies (2000)
Bazaliy, Ya. B., Jones, B. A., Zhang, Shou-Cheng
Several recent experimental studies have confirmed the possibility of switching the magnetization direction in the small magnetic domains by pumping large spin-polarized currents through them. On the...
Stripe Formation within SO(5) Theory (1998)
Veillette, M., Bazaliy, Ya. B., Berlinsky, A. J., Kallin, C.
We study the formation of stripe order within the SO(5) theory of high T_c superconductivity. We show that spin and charge modulations arise as a result of the competition between a local tendency to...
Bazaliy, Ya. B., Jones, B. A., Zhang, Shou-Cheng
We derive a continuum equation for the magnetization of a conducting ferromagnet in the presence of a spin-polarized current. Current effects enter in the form of a topological term in the...
Staggered Superconductivity in UPt$_3$: A New Phenomenological Approach (1994)
Heid, R., Bazaliy, Ya. B., Martisovitsi, V., Cox, D. L.
We present a new Ginzburg-Landau theory for superconductivity in UPt$_3$, based upon a multicomponent order parameter transforming under an irreducible space group representation; the phase is...
