Comment on ''Alternating spin and orbital dimerization and spin-gap formation in coupled spin-orbital systems''
R. J. Radwanski, Z. Ropka
Abstract
By this Comment we would like to point out [2] that, though such consideration can be quite sophisticated, the consideration of a spin-pseudo-spin Hamiltonian has nothing in common with the reality. It means that such the consideration are useless as far as the properties of real systems are concerned.
