Nonequilibrium dynamical behavior in noncoplanar magnets with chiral spin texture
نویسندگان
چکیده
We observe nonequilibrium dynamical magnetic behavior in the magnetically ordered phase of a Tsai-type Tb-Au-Si quasicrystal approximant system. The texture is found to exhibit scalar spin chirality (SSC) order, inferring that SSC order parameter present further find introduction ``pseudo-Tsai'' clusters, associated with additional Tb atoms structure, induces spin-glass dynamics. discuss observed systems, considering effect pseudo-Tsai clusters on configuration and local chirality.

Nonlinear spin relaxation in strongly nonequilibrium magnets
A general theory is developed for describing the nonlinear relaxation of spin systems from a strongly nonequilibrium initial state, when, in addition, the sample is coupled to a resonator. Such processes are characterized by nonlinear stochastic differential equations. This makes these strongly nonequilibrium processes principally different from the spin relaxation close to an equilibrium state...
متن کاملDriven Skyrmions and dynamical transitions in chiral magnets.
We study the dynamics of Skyrmions in chiral magnets in the presence of a spin polarized current. The motion of Skyrmions in the ferromagnetic background excites spin waves and contributes to additional damping. At a large current, the spin wave spectrum becomes gapless and Skyrmions are created dynamically from the ferromagnetic state. At an even higher current, these Skyrmions are strongly de...
متن کاملTunable chiral spin texture in magnetic domain-walls
Magnetic domain-walls (DWs) with a preferred chirality exhibit very efficient current-driven motion. Since structural inversion asymmetry (SIA) is required for their stability, the observation of chiral domain walls in highly symmetric Pt/Co/Pt is intriguing. Here, we tune the layer asymmetry in this system and observe, by current-assisted DW depinning experiments, a small chiral field which se...
متن کاملChiral scattering in complex magnets
General properties of the chiral scattering of polarized neutrons are considered for two possible axial vector interactions: Zeeman energy and non-alternating DzyaloshinskiiMoriya interaction. Behavior in magnetic field of helical magnetic structures is discussed for MnSi and magneto-electric materials. The dynamical chiral fluctuations in magnetic field are considered briefly. The chiral fluct...
متن کاملMasses of spin-1 mesons and dynamical chiral symmetry breaking
In terms of an effective chiral theory of mesons it is shown quantitatively that in the limit of mq = 0, the masses of ρ, ω, K (892), mφ, a1, f1(1286), K1(1400), and f1(1510) mesons originate from dynamical chiral symmetry breaking.
