BASICS OF SPIN WAVE THEORY
Journal Title: Journal of Science And Arts - Year 2011, Vol 17, Issue 4
Abstract
Developed in the 50's, the spin waves theory is one of the milestones in magnetism and continues to be of fundamental importance. This approach allows a physically appealing treatment of long range magnetically ordered phases, where the quantum effects enter as time dependent fluctuations about the classical ground state. Spin waves can thus be seen as time dependent phenomena, actually corresponding to precession modes of the magnetically ordered structure, with typical energies of a few meV (or THz).

ENERGY DISPERSIVE X-RAY FLUORESCENCE (EDXRF) ANALYSIS OF STEELS
A powerful, simple and fast technique for non-destructive multi-element analysis of materials is energy dispersive X-ray fluorescence (EDXRF) technique. This method is based on radioisotope excited energy dispersive X-ra...
ON THE REPRESENTATION OF A H1 (a, b) DISTRIBUTION THAT FULFILS u (a) = 0
We define the closed cone of increasing functions and represent each u as a sum of its projection on cone and the remaining part. We then define a scalar product and prove that the induced norm convergence implies the un...
ON THE MONOTONY OF (1+1/n)^n+0.5 AND AN APPLICATION
In this paper we expose two different proofs for the fact that the sequence of general term (1+1/n^)n+0.5which convergesto the celebrated constant of Napier also called the number of Euler, the number e, is strictly decr...
FINITENESS PROPERTIES FOR THE PATH COALGEBRA ASSOCIATED TO A POSET
Let P be a partially ordered set (poset) locally finite and kQ the path coalgebra over a field k associated to P. In this paper we investigate finiteness properties of this coalgebra by using an injective morphism of coa...
