Magnetic proximity effect at Bi${}_2$Se${}_3$/EuS interface with broken inversion symmetry

Alex Taekyung Lee, Myung Joon Han, Kyungwha Park

We investigate a magnetic proximity effect on Dirac surface states of topological insulator (TI) induced by a Bi${}_2$Se${}_3$/EuS interface, using density-functional theory (DFT) and…
