Magnetic properties of (ZnO)_1/(CuO)_1 (001) superlattice

摘要

The magnetic properties of (ZnO)_1/(CuO)_1 (001) superlattice have been investigated by means of ab initio calculations based on spin density functional theory. The ZnO/CuO superlattice is found to be spin polarized, and the calculated band structure suggests a 100% polarization of the conduction carriers. The analysis of the partial density of states reveals that ferromagnetism can be explained here by the strong p-d hybridization of O and Cu.
