Résumé:
The CoPt binary alloy, due to its tetragonal L10 structure, shows a strong
magnetic anisotropy, and is a good candidate for ultra high density informatics storage
device. We present in this work ab initio calculations of the stability, and magnetic
properties of CoPt L10 alloy in the ferromagnetic states, and we have focused our study on
the (001) surfaces and the influence of stacking faults. Our results show that magnetism is
enhanced in surface
