Hi Padmaja, you need write in the input file the next variables:<br><br>&system<br><div style="margin-left: 40px;">starting_magnetization(1) = 0.00<br></div><div style="margin-left: 40px;">starting_magnetization(2) = 0.00<br>
starting_magnetization(3) = 0.00<br>-....<br>starting_magnetization(i) = 1.00,<br>starting_magnetization(j) = -1.00,<br></div><br>where "i" and "j" is the number of the two impurity atoms, although in different spin direccion. If the other atoms in your supercell aren't magnetics, just write 0.0. Furthermore, you have to write twice the pseudopotential belonging to the impurity. For example:<br>
<br>ATOMIC_SPECIES<br>......<br>........<br> Fe1 55.845 Fe.pbe-paw_kj.UPF<br> Fe2 55.845 Fe.pbe-paw_kj.UPF<br><br>Best.<br><br>Arles V. Gil Rebaza<br>Instituto de Física de La Plata<br>La Plata - Argentina<br><br><br>

<table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font:inherit" valign="top">Hi All<br><br>I want to do calculations on a supercell where I am adding two impurity atoms of the same kind at two different places. I want to make sure that these two atoms are in opposite spins. how can I format the input file to achieve this condition. And also if somebody knows any software which can plot the atomic structure along with the spins direction then please let me know.<br>
<br>Thanking you in advance.<br><br>Regards<br><font color="#888888">Padmaja Patnaik<br>
