Abstract:
We present experimental data for the Raman intensity in the spin-Peierls
compound CuGeO3 and theoretical calculations from a one-dimensional
frustrated spin model, The theory is based on (a) exact diagonalization
and (b) a recently developed solitonic mean-field theory. We find good
agreement between the one-dimensional theory in the homogeneous phase
and evidence for an interesting dimerization of the Raman operator in
the spin-Peierls state. Finally we present evidence for a coupling
between the interchain exchange, the spin-Peierls order parameter, and
the magnetic excitations dong the chains.
