This looks fine to me

Hi all,

sorry to bother, I have some trouble with the parameter definition in my models Hamiltonian. Could someone help look at the "BONDTERM" and particularly the specification of parameter? In the examples in the tutorials, I saw that another set of parameters is defined in every type of bondterm, and the default values of these parameters are referred the parameters defined in the beginning.

Because my model Hamiltonian is the Heisenberg's model with Dzyaloshinski-Moriya interaction, so I didn't introduce new parameters for each bond (named as J#), and simply use the parameters defined in the beginning. Can I do this? Is my definition correct?

If there is something wrong in the lattice and model definition, could you help correct them?

Thanks a lot. Gang <model.xml> <Hkcluster.xml> <parm.tex>
