| Research Abstract |
Understanding and controlling spin strictures at surfaces/interfaces has increased because of their potential technological importance. Here, from the first principles FLAPW calculations, we demonstrated i) half-metallicity at exchange bias ferromagnetic/antiferromagnetic interfaces of CrSe/MnSe and CrTe/MnTe, ii) magnetic structures at Cr_2O_3/Pt and Fe/MgO interfaces as a possibly useful candidate of magneto electric materials, and iii) magneto crystalline anisotropy and stability of spin-spiral structures in thin film transition-metals, and we furthermore developed iv) a method to treat structural and magnetic stability at finite temperatures.
