<DIV><FONT face=Arial size=2>Dear Wien users <BR>We are making some
calculations in perovskites systems, in particular <BR>to analyze the
magnetic moment of metals like Cu and Co in <BR>different
environments. <BR>After study of several examples, we found for
oxygen a non-zero <BR>magnetic moment (0.17 muB approx.) inside its
rmt (rmt=1.5 for Oxygen). <BR>What could be the reason of
that? <BR>Best Regards <BR>Ricardo <BR></FONT></DIV>
