    Dear all,<br>
    <br>
    I work on Boron Nitride structures and got confused about the use
    spin polarization in that case.<br>
    Well, some people say that one have to but I have papers which
    described DFT calculations on BN without it. <br>
    So, I'm wondering how much spin polarization influence the cell
    relaxation and scf calculations, and whether it has some influence
    on phonon for instance.<br>
    Thank you,<br>
    <br>
