Solitarywaves on finite-size antiferromagnetic quantumHeisenberg spin rings
نویسندگان
چکیده
Motivated by the successful synthesis of several molecular quantum spin rings we are investigating whether such systems can host magnetic solitary waves. The small size of these spin systems forbids the application of a classical or continuum limit. We therefore investigate whether the time-dependent Schrödinger equation itself permits solitary waves. Example solutions are obtained via complete diagonalization of the underlying Heisenberg Hamiltonian. c © 2008 Elsevier B.V. All rights reserved. PACS: 75.10.Jm; 05.45.Yv; 75.50.Ee; 75.50.Xx

Standing Spin Waves in an Antiferromagnetic Molecular Cr6 Horseshoe
The antiferromagnetic molecular finite chain Cr6 was studied by inelastic neutron scattering. The observed magnetic excitations at 2.6 and 4.3 meV correspond, due to the open boundaries of a finite chain, to standing spin waves. The determined energy spectrum revealed an essentially classical spin structure. Hence, various spin-wave theories were investigated in order to assess their potential ...

In this paper a simple model calculation of spin wave is given for the ferromagtic layer in ultra thin ferromagnetic/antiferromagnetic bilayer. In this model the magnetic layer is assumed as an isolated layer but the effect of antiferromagnetic layer on ferromagnetic layer and unidirectional anisotropy, is given in the effective field applied on each spin. The thin layer is assumed as two-dim...
متن کاملPersistent spin currents in mesoscopic Haldane-gap spin rings
Using a modified spin-wave approach, we show that in the presence of an inhomogeneous magnetic field or an in-plane inhomogeneous electric field a mesoscopic antiferromagnetic Heisenberg ring with integer spin ~i.e., a Haldane-gap system! exhibits a persistent circulating spin current. Due to quantum fluctuations the current has a finite limit on the order of (2gmB)c/L at zero temperature, prov...
متن کاملExcitation Spectrum of the Spin-1/2 Ferromagnetic-Antiferromagnetic Alternating Heisenberg Chain
The natural explanation of the excitation spectrum of the spin1 antiferromagnetic Heisenberg chain is given from the viewpoint of the spin-1/2 ferromagnetic-antiferromagnetic alternating Heisenberg chain. The energy spectrum of the latter is calculated with fixed momentum k by numerical diagonalization of finite size systems. It consists of a branch of propagating triplet pair (triplet wave) an...
متن کاملEntanglement in supramolecular spin systems of two weakly coupled antiferromagnetic rings (purple-Cr7Ni).
We characterize supramolecular magnetic structures, consisting of two weakly coupled antiferromagnetic rings, by low-temperature specific heat, susceptibility, magnetization and electron paramagnetic resonance measurements. Intra- and inter-ring interactions are modeled through a microscopic spin-Hamiltonian approach that reproduces all the experimental data quantitatively and legitimates the u...
