Comment on "magnetoelastic model for the relaxation of lanthanide ions in YBa2Cu3O7-δ observed by neutron scattering"

Physical Review B Condensed Matter and Materials Physics 64:6 (2001) 665011-665014

Abstract:

Lovesey and Staub have argued [S.W. Lovesey and U. Staub, Phys. Rev. B 61, 9130 (2000)] that experimental data on the temperature dependence of the paramagnetic relaxation of lanthanide ions doped into YBa2Cu3O6+x are in agreement with the predictions of a model that describes the relaxation as due to the scattering of phonons via a magnetoelastic interaction. By generalizing their model I show that the level of agreement is strongly dependent on the number of intermediate lanthanide energy levels included in the calculation, and that inclusion of a more complete set of levels leads to very different results that do not necessarily support the phonon damping picture.
