you Heather and Jia for your replies. For a single Co atom, I do get the
total magnetization of 3 but when Co is on a surface, its spin
polarization comes out to be 2, which is S=1. The all-electron
calculations were also done using pbe functional and on the same
surface and with the same coverage of Co.<br><br>Heather, what do you mean by
locally? I do calculate the spin polarization from pdos. The whole
system does have an even number of electrons but why does it result in
S=1? Any explanation would be appreciated.</span></font></font><font size="3"><br><br>-- <br></font><font size="3">Izaak Williamson</font><font size="3"><br>Research Assistant<br>Physics Department<br>Boise State University</font><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br></div></div></body></html>
