Thickness dependence of Fe 3O 4/MgO thin film properties: Density functional theory investigation

In this work, the thickness dependence of Fe3O 4(111)/MgO thin films, were simulated using density-functional theory. From the results, even though the total DOS in bulk structure presents a half-metallic behavior, the DOS of all Fe3O4 (111) films demonstrates that they are metallic. The specific ma...
