Rectangular and square skyrmion crystals on a centrosymmetric square lattice with easy-axis anisotropy

چکیده
We report our theoretical results on the emergence of rectangular- and square-shaped magnetic skyrmion crystals a centrosymmetric square lattice with anisotropy. By performing simulated annealing for frustrated spin model an easy-axis single-ion anisotropy lattice, we find that competition interactions in momentum space gives rise to formation two crystals, where cores are aligned rectangle- or square-lattice way. Especially, at higher harmonic wave vectors play important role stabilizing square/rectangular crystals. Our provide reference explore further skyrmion-hosting materials tetragonal systems.

A Novel Structure for Optical Channel Drop Filter using Two-Dimensional Photonic Crystals with Square Lattice
In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...
متن کاملInfluence of anisotropy on percolation and jamming of linear k-mers on square lattice with defects
By means of the Monte Carlo simulation, we study the layers produced by the random sequential adsorption of the linear rigid objects (k-mers also known as rigid or stiff rods, sticks, needles) onto the square lattice with defects in the presence of an external field. The value of k varies from 2 to 32. The point defects randomly and uniformly placed on the substrate hinder adsorption of the elo...
متن کاملTetramers with vacancies on the square lattice
Two-dimensional dimer models were introduced in statistical mechanics in the 1930s to study the adsorption of diatomic molecules on a surface [1]. In its basic formulation, a dimer on a two-dimensional lattice is an object that lives on a bond b between two nearest-neighbour sites with some associated activity zb = exp−εb/kT where εb may be thought of as the adsorption energy of the dimer. The ...
متن کاملConditions for waveguide decoupling in square-lattice photonic crystals
We study coupling and decoupling of parallel waveguides in two-dimensional square-lattice photonic crystals. We show that the waveguide coupling is prohibited at some wavelengths when there is an odd number of rows between the waveguides. In contrast, decoupling does not take place when there is even number of rows between the waveguides. Decoupling can be used to avoid cross talk between adjac...
متن کاملMagnetostatic interactions on a square lattice
The metastable zero field magnetic states of elongated Permalloy islands on square lattices of different geometries are investigated by means of magnetic force microscopy and numerical calculations. Keeping the island shape L /w=10 fixed while varying the interparticle distances a, it is demonstrated that the relative frequencies of observed magnetic configuration at remanence strongly depend o...
