[Wien] "overmagnetisation" of GGA

[thomas.mazet]

Dear Wienusers,

 I'm doing GGA and LDA computations on transition metal intermetallics, 
and I found (in fact, the computer) that the Fe spin moment is about 
20-30% higher with GGA compare to LDA. 
 Such an effect has been previously reported in the litterature, but I 
don't have the relevant references.
 Could someone provide me some of these references ? Comments of 
experienced users are also welcome.

Thanks in advance.
Regards,

Thomas
