<DIV>As atomic and ionic crystal radii depend strongly to the their
environment and vary from one case to another, the localization or
delocalization of f-electrons also vary from one case to
another. Thus keeping in mind the following two points may be
helpful:</DIV>
<DIV>1. We must always make sure about the localization or delocalization
behavior of f-electrons in an specific case, and do not try to generalize the
behavior of f-electrons from one case to all the other cases.</DIV>
<DIV>2. There are many insensitive parameters to correlation of strongly
correlated electrons so that making sure about the behavior using them does not
make sense.</DIV>
<DIV> </DIV></DIV>

<DIV><BR></DIV>
<DIV>Dear wien users,</DIV>
<DIV>Hello. I'd like to know if it is alright to use the GGA method to study
the structural and magnetic phase stability of lanthanide metallic compounds?
I have already applied it ( not including SO ) to many cases and the results
are in very very good agreement with the existing experimental data.</DIV>
<DIV>Thank you.</DIV>
