Hi,
is it possible to define a kind of 'Ising-type' or Potts-like model for the 3D Heisenberg MC simulation as in PRB 72,134426, where the unit vectors are restricted to lie on a cone defined by a discrete spin-z-component Sz=-S,...+S? For S=1/2 this would correspond to the usual Ising model.
Is it possible to define therefor a spin number, lets say S, so that the z-component is restricted to have a value between -S and +S where the x- and y-components are still chosen randomly?
Best and thanks for the great support! Fritz
