# Magnetic exchange interaction by first principle (Blume-Capel model)

• A
Hi guys.

I work with statistichal mechanics, applying classical spin models, as Ising model. I'm trying a collaboration with a collegue that works with first principle calculations. Does anyone know how to calculate the exchange interaction and anisotropic constant (of the Blume-Capel model), of bulk materials, by first principle??

Thanks a lot !!
