0924-6339 ith restricted dimensionality d as an object that is infinite only in one or two spatial directions (d = 1 and 2). Such a definition comprises isolated single chains or layers, but also fibres and thin layers (films) of varying but finite thickness. Clearly, a multitude of physical phenomena, notabl

Spin Waves in Two-Dimensional Magnetic Systems: Theory And Applications,-wavelength modes of these precessions have energies near zero. These concepts were first introduced by Bloch . Presently, assuming the presence of translational invariance, we commonly refer to these motions as spin waves, or the quantum-mechanical equivalent, magnons.
