Magnon-magnon interactions in the Spin-Peierls compound CuGeO_3
C. Gros, W. Wenzel, A. Fledderjohann +6
In a magnetic substance the gap in the Raman spectrum, Delta_R, is approximatively twice the value of the neutron scattering gap, Delta_S, if the the magnetic excitations (magnons)…
Substitution effects on spin fluctuations in the spin-Peierls compound CuGeO_3
M. Fischer, P. Lemmens, G. Güntherodt +4
Using Raman scattering we studied the effect of substitutions on 1D spin fluctuations in CuGeO_3 observed as a spinon continuum in frustration induced exchange scattering. For temp…
The J_1-J_2 model revisited : Phenomenology of CuGeO_3
V. N. Muthukumar, Claudius Gros, Roser Valenti +6
We present a mean field solution of the antiferromagnetic Heisenberg chain with nearest (J_1) and next to nearest neighbor (J_2) interactions. This solution provides a way to estim…
