[ESPResSo-users] magnetic field due to magnetic dipoles

[tomaž mohorič]

Dear all,

I am a new user of Espresso and I would have a question
 for more experienced users. I read the documentation (user's guide) but
 couldn't find the answer. 

I would like to simulate a system of 
magnetic dipoles. As far as I understood, Espresso is able to calculate 
the energy of such a system and forces acting on each particle. 

In my case I would like to know what is the magnetic field (due to 
all other dipoles) at the position of each particle. Problem is not so 
trivial, since the magnetic field due to magnetic dipole decreases as 
1/r**3 and one should take into account contribution from all particles 
(for beginning I assume repeating cells in x and y axis). 

Previously I studied simpler systems and I know that magnetic field due to other dipoles may increase magnetic moments by 20%.

My question is: is there any way to obtain the magnetic field due to magnetic dipoles from Espresso?


Thanks for your help and kind regards.
