How to Construct AFM and FM magnetic ordering in CASTEP code implemented in materials studio software?
In rutile TiO2, I want to calculate the ferromagnetic coupling and antiferromagnetic coupling of two Oxygen vacancies (VO), calculate Curie temperature through ΔE=EFM-EAFM,
Could ayone please explain how to construct ferromagnetic coupling and antiferromagnetic coupling containing two VO in materials studio software?
