Mechanical behaviour of motion for the two-dimensional monolayer system‎

‎In this paper we study the dynamics of the 2D-motion of a particle of monolayer‎. First we consider the usual physical time component and the plan manifold R2, having the polar coordinates. Then a geometric approach to nonholonomic constrained mechanical systems is applied to a problem from the two dimensional geometric dynamics of the Langmuir-Blodgett monolayer‎. We consider a constraint sub...

Magnons in a ferromagnetic monolayer.

We report the first observation of high wave vector magnon excitations in a ferromagnetic monolayer. Using spin-polarized electron energy loss spectroscopy, we observed the magnon dispersion in one atomic layer (ML) of Fe on W(110) at 120 K. The magnon energies are small in comparison to the bulk and surface Fe(110) excitations. We find an exchange parameter and magnetic anisotropy similar to t...

Ferromagnetic Nanoclusters in two-dimensional He

He adsorbed on graphite is an almost ideal two dimensional (2D) fermionic system. The 2D solid, where the interaction between the nuclear spins S = 1 2 is due to multiple spin exchange, has been extensively studied as a model system for strongly interacting fermions in 2D. At high densities in the second layer, three body exchange dominates and leads to Heisenberg ferromagnetism. We report on N...

Antiplane Shear Waves in Two Contacting Ferromagnetic Half Spaces

The problem of reflection and refraction of antiplane shear (or magneto-elastic) waves at the interface between two ferromagnetic half-spaces with slipping contact (vacuum gap) is studied for waves propagating normal to the direction of the applied external magnetic field which is assumed to be parallel to the interface. We show the existence of new waves that are localized near the interface b...
