Thank you Prof Blaha for your answer I have found this textbook presented by your person ( textbook <https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=6&cad=rja&uact=8&ved=0ahUKEwiKtvOmr_nQAhVHXBQKHZBMBK8QFghBMAU&url=http%3A%2F%2Fsusi.theochem.tuwien.ac.at%2Fevents%2Fws2003%2Fdownloads%2Fws2003_blaha.ppt&usg=AFQjCNEhpxUeuzW3eaRuSEVJdJP3jTXVLQ&sig2=O9V7LlxUAmxv4NnuZM9qjw&bvm=bv.142059868,bs.2,d.d2s> ).
Now I want to know the following: - The Self interaction Correction *SIC* variant is the same the Full Localized Limit FLL variant ? - When putting U=0 and J=0 ? I have found a result different from the LDA method GGA ---> magnetic ground state = non magnetic GGA+U (U+J=0 ) ----> magnetic groud state = antiferromagnetic state with little difference with non magnetic state. Why ? Best regards -- Mr: A.Reggad Laboratoire de Génie Physique Université Ibn Khaldoun - Tiaret Adresse: BP 144 AL ATTAF AIN DEFLA Tel: +213(0)561861963 Algerie
