Dear Alps Users, I am trying to simulate a binary ferromagnetic system i.e FeCo. I am running the classical monte carlo simulations by using the classical Heisenberg model . I am using the spinmc binary for my task.
My confusion is regarding the double counting aspect of the Heisenberg model. since i have FeCo as the binary system. I will have two set of edges , which are as follows: Set 1 : { Fe-Fe, Fe-Co, Co-Co}
Set 2 : {Fe-Fe, Fe-Co, Co-Fe, Co-Co}.
My question is, In order to simulate the FeCo system correctly should i consider the edge Fe-Co ( J= 25 meV) only once OR should i consider both F e-Co and Co-Fe (J= 50 mev).
I have tried to locate the exact equation of the Heisenberg Hamiltonian which is being used for the classical monte carlo simulation, but unfortunately i could not find this information. is the double counting aspect already taken care in the ALPS simulations. if so, then i think i have to define both Fe-Co and Co-Fe edges for the simulation. I am kindly requesting you to provide me insight into this aspect.
I am caught up with this confusion, which is stopping me from proceeding further. Therefore, I am kindly requesting you to provide me your suggestions and help regarding the above mentioned issue.
I thank you in advance for your kind consideration and time.
with best regards Sunil
