We develop a theory of electromagnons in CuO by combining a symmetry analysis based on irreducible corepresentations, ab initio calculations, and simulations of spin dynamics using a model Hamiltonian and the Landau-Lifshitz-Gilbert equation. We show that the electromagnon measured in [Jones et al., Nat. Commun. 5, 3787 (2014)] with the electric field along the [101] direction originates from a...
The magnetically induced electric polarization behaviors in multiferroic TmMn2O5 in response to varying temperature and magnetic field are carefully investigated by means of a series of characterizations including the high precision pyroelectric current technique. Here polycrystalline rather than single crystal samples are used for avoiding the strong electrically self-polarized effect in singl...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
In this paper, an isomorphism between unit dual sphere, DS2, and the subset of tangent bundle 2-sphere, T?M, is represented. According to E. Study mapping, a ruled surface in IR3 corresponds each curve on DS2. Through isomorphism, new forms surfaces called slant were introduced. Moreover, conditions for these be given. Finally, unique ?q?,?h? ?? corresponded striction natural lift T?M.
In this paper, parallel q-equidistant ruled surfaces are defined such that the binormal vectors of given two differentiable curves along striction their corresponding surfaces, and distance between asymptotic planes is constant at proper points, which related to symmetry. The characterizations some other useful relations drawn for these as well. If considered be closed, then integral invariants...
