'magnetization' problem in the DFT+U
Posted: Mon Jul 06, 2015 3:46 pm
Dear All,
There is a problem when I do a ground state calculation of Eu2+ doped compound.
There are 7electrons in the 4f state of Eu2+ ion. Thus, the 'magnectization' should be equal to 7. However, In my calculation, magnetization=1 was obtianed. How I can do for deleting such error?
In the calculation,
1. the U value is set to be 4eV, which successfully locate the Eu4f state between the VBM and CBM.
2. The spin-polarizaiton has been consided, in which the 'spinat' was set to 0 0 7.
Thanks for the help.
Best wishes,
Yongchao
