Anisotropic magnetic interactions and spin dynamics in the spin-chain compound Cu(py)Br: An experimental and theoretical study
J. Zeisner, M. Brockmann, S. Zimmermann +9
We compare theoretical results for electron spin resonance (ESR) properties of the Heisenberg-Ising Hamiltonian with ESR experiments on the quasi-one-dimensional magnet Cu(py)B…
Orbital-Exchange and Fractional Quantum Number Excitations in an f-electron Metal YbPtPb
L. S. Wu, W. J. Gannon, I. A. Zaliznyak +9
Exotic quantum states and fractionalized magnetic excitations, such as spinons in one-dimensional chains, are generally viewed as belonging to the domain of 3d transition metal sys…
Exact description of the magnetoelectric effect in the spin-1/2 XXZ-chain with Dzyaloshinskii-Moriya interaction
Michael Brockmann, Andreas Klümper, Vadim Ohanyan
We consider a simple integrable model of a spin chain exhibiting the Magnetoelectric Effect (MEE). Starting from the periodic S=1/2 XXZ-chain with Dzyaloshinskii-Moriya terms, whic…
On the theory of microwave absorption by the spin-1/2 Heisenberg-Ising magnet
Michael Brockmann, Frank Göhmann, Michael Karbach +2
We analyze the problem of microwave absorption by the Heisenberg-Ising magnet in terms of shifted moments of the imaginary part of the dynamical susceptibility. When both, the Zeem…
