Magnetization Relaxation and Collective Spin Excitations in Correlated Double--Exchange Ferromagnets
M. D. Kapetanakis, I. E. Perakis
We study spin relaxation and dynamics of collective spin excitations in correlated double--exchange ferromagnets. For this, we introduce an expansion of the Green's functions equat…

Spin dynamics in (III,Mn)V ferromagnetic semiconductors: the role of correlations
M. D. Kapetanakis, I. E. Perakis
We address the role of correlations between spin and charge degrees of freedom on the dynamical properties of ferromagnetic systems governed by the magnetic exchange interaction be…

Non--Heisenberg Spin Dynamics of Double-Exchange Ferromagnets with Coulomb Repulsion
M. D. Kapetanakis, I. E. Perakis
With a variational three--body calculation we study the role of the interplay between the onsite Coulomb, Hund's rule, and superexchange interactions on the spinwave excitation spe…
