Decomposed bloch walls in iron

چکیده
2014 The magnetoelastic problem of a zig-zag 90° Bloch wall in iron is studied, either for a (110) or (001) wall. The elastic strains, due to magnetostriction, are calculated in both cases. The total energy of a zig-zag wall is obtained by adding, to the usual anisotropy and exchange contributions, the elastic term. Thus we find the equilibrium values for the periodicity and the angle of the zig-zag. Finally, we briefly discuss the contrast observed by X-ray diffraction topography of (110) walls for 110 reflexions.

2 5 Fe b 19 99 Mobility of Bloch Walls via the Collective Coordinate Method
We have studied the problem of the dissipative motion of Bloch walls considering a totally anisotropic one dimensional spin chain in the presence of a magnetic field. Using the so-called “collective coordinate method” we construct an effective Hamiltonian for the Bloch wall coupled to the magnetic excitations of the system. It allows us to analyze the Brownian motion of the wall in terms of the...
متن کاملPhase-locked spatial domains and Bloch domain walls in type-II optical parametric oscillators.
We study the role of transverse spatial degrees of freedom in the dynamics of signal-idler phase locked states in type-II optical parametric oscillators. Phase locking stems from signal-idler polarization coupling which arises if the cavity birefringence and/or dichroism is not matched to the nonlinear crystal birefringence. Spontaneous Bloch domain wall formation is observed numerically and th...
متن کاملInteractions of parametrically driven dark solitons. I. Néel-Néel and Bloch-Bloch interactions.
We study interactions between the dark solitons of the parametrically driven nonlinear Schrödinger equation, Eq. 1 . When the driving strength, h , is below sqrt[gamma(2)+1/9], two well-separated Néel walls may repel or attract. They repel if their initial separation 2z(0) is larger than the distance 2zu between the constituents in the unstable stationary complex of two walls. They attract and ...
متن کاملStability for Static Walls in Ferromagnetic Nanowires
The goal of this article is to analyze the time asymptotic stability of one dimensional Bloch walls in ferromagnetic materials. The equation involved in modelling such materials is the Landau-Lifchitz system which is non-linear and parabolic. We demonstrate that the equilibrium states called Bloch walls are asymptotically stable modulo a rotation and a translation transverse to the wall. The li...
متن کاملBloch oscillations of magnetic solitons in anisotropic spin - 12 chains
We study the quantum dynamics of solitonlike domain walls in anisotropic spin1 2 chains in the presence of magnetic fields. In the absence of fields, domain walls form a Bloch band of delocalized quantum states while a static field applied along the easy axis localizes them into Wannier wave packets and causes them to execute Bloch oscillations, i.e., the domain walls oscillate along the chain ...
