Longitudinal magnetization dynamics in Heisenberg magnets: Spin Green functions approach
In spite of the fact that dynamical properties of magnets have been extensively studied over the past years, the longitudinal magnetization dynamics is still much less understood than transverse one even in the equilibrium state of a system. In this paper, we give a review of existing, based on quan...

| description | In spite of the fact that dynamical properties of magnets have been extensively studied over the past years, the longitudinal magnetization dynamics is still much less understood than transverse one even in the equilibrium state of a system. In this paper, we give a review of existing, based on quantum-mechanical approach, theoretical descriptions of the longitudinal magnetization dynamics for ferro-, ferri- and antiferromagnetic dielectrics. The aim is to reveal specific features of this type of magnetization vibrations under description a system within the framework of one of the basic model theory of magnetism— the Heisenberg model. Related experimental investigations as well as open questions are also briefly discussed. We hope that understanding of the longitudinal magnetization dynamics distinctive features in the equilibrium state have to be a reference point for a theory uncovering the physical mechanisms that govern ultrafast spin dynamics after femtosecond laser pulse demagnetization when a system is far beyond an equilibrium state.

The author dedicates this article to the memory of
 Anatolii Illarionovich Zvyagin; in 1984–1990 I had the
 opportunity to participate in the work of scientific group
 led by A.I. Zvyagin on searching and investigating new
 types of magnetic structures and resonances in low-dimensional multiple sublattice antiferromagnets. The author is
 grateful for valuable discussions with V.G. Bar’yakhtar
 and B.A. Ivanov; I also extend appreciation to M. Belogolovskii for reading the manuscript and critical remarks.
