<html><head></head><body>Dear Gavin<br><br>Thanks a lot for your reply. I check that previous post. But as i understand when we set the "number of choices" equal to 2 we can add two plasma frequencies in .inkram but this compound is a cubic and "number of choices" should be 1. In half metals each spin have a different band structure and plasma frequency. Accordingly is this correct to do add two plasma frequencies for each spin in .inkram.<br><br>sincerely yours.<br></body></html>
