Dear Patnaik i dont know whether i can give you proper answer but i did observe some papers by weht and pickett and Galankis papers on Heusler alloys systems they observed negative magnetic moment...Since Z direction is field direction you can have negative magnetic moment...please check the area under curve for spin down and spin up sub bands (for both positive and negative cases u can get plausible explanation)....
hope this helps With regards K. Ramesh Kumar Research Scholar Department of Physics IIT-Madras Chennai-600 036 -------------- next part -------------- An HTML attachment was scrubbed... URL: http://www.democritos.it/pipermail/pw_forum/attachments/20100825/6dae17a0/attachment.htm
