Spin waves in rings of classical magnetic dipoles
H. -J. Schmidt, C. Schröder, M. Luban
We theoretically and numerically investigate spin waves that occur in systems of classical magnetic dipoles that are arranged at the vertices of a regular polygon and interact sole…
Dynamics and thermodynamics of a pair of interacting magnetic dipoles
Heinz-Jürgen Schmidt, Christian Schröder, Eva Hägele +1
We consider the dynamics and thermodynamics of a pair of magnetic dipoles interacting via their magnetic fields. We consider only the "spin" degrees of freedom; the dipoles are fix…
Exchange randomness and spin dynamics in the frustrated magnetic Keplerate {W72V30}
J. Schnack, A. M. Todea, A. Müller +5
The magnetic properties and spin dynamics of the spin frustrated polyoxometalate {W72V30}, where 30 V^{4+} ions (s = 1/2) occupy the sites of an icosidodecahedron, have been invest…
Determination of exchange energies in the sawtooth spin ring {Mo75V20} by ESR
Yugo Oshima, Hiroyuki Nojiri, Jürgen Schnack +2
The magnetism of the polyoxometalate cluster {Mo75V20}, containing a sawtooth ring of 10 corner-sharing triangles located on the equator of the barrel-shaped molecule, has remained…
Theory of severe slowdown in the relaxation of rings and clusters with antiferromagnetic interactions
Ioannis Rousochatzakis, Andreas Laeuchli, Ferdinando Borsa +1
We show that in the severe slowing down temperature regime the relaxation of antiferromagnetic rings and similar magnetic nanoclusters is governed by the quasi-continuum portion of…
Modulated spin waves and robust quasi-solitons in classical Heisenberg rings
Heinz-Jürgen Schmidt, Christian Schröder, Marshall Luban
We investigate the dynamical behavior of finite rings of classical spin vectors interacting via nearest-neighbor isotropic exchange in an external magnetic field. Our approach is t…
