Our calculated results shown that the spin magnetic moments and the orbital magnetic moments increase linearly with increasing U and J. While the interesting behaviour appears when volume compression is greater than 70% for NiO and 50% for MnO at which ms collapses. Further increase of volume compression to be at 80% leads to the disappearance of both magnetic moments.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {6}, number = {3}, year = {2012}, pages = {330 - 332}, ee = {https://publications.waset.org/pdf/2921}, url = {https://publications.waset.org/vol/63}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 63, 2012}, }
