Resumen:
We investigate a simple model of a frustrated classical spin chain
coupled to
adiabatic phonons under an external magnetic field. A thorough study of
the
magnetization properties is carried out both numerically and
analytically. We
show that already a moderate coupling with the lattice can stabilize a
plateau
at 1/3 of the saturation and discuss the deformation of the underlying
lattice
in this phase. We also study the transition to saturation where either a
first
or second order transition can occur, depending on the couplings
strength.
