Perovskite-type cobalt oxide at the multiferroic Co/Pb ZrTiO interface
K. Mohseni, A. Polyakov, H. B. Vasili +13
Magnetic Tunnel Junctions whose basic element consists of two ferromagnetic electrodes separated by an insulating non-magnetic barrier have become intensely studied and used in non…
A Charge-Density-Wave Topological Semimetal
Wujun Shi, Benjamin J. Wieder, H. L. Meyerheim +14
Topological physics and strong electron-electron correlations in quantum materials are typically studied independently. However, there have been rapid recent developments in quantu…
Instability of the topological surface state in BiSe upon deposition of gold
A. Polyakov, C. Tusche, M. Ellguth +10
Momentum resolved photoemission spectroscopy indicates the instability of the Dirac surface state upon deposition of gold on the (0001) surface of the topological insulator BiS…
Jahn-Teller stabilization of a "polar" metal oxide surface: Fe3O4(001)
R. Pentcheva, F. Wendler, H. L. Meyerheim +3
Using ab initio thermodynamics we compile a phase diagram for the surface of Fe3O4(001) as a function of temperature and oxygen pressures. A hitherto ignored polar termination with…
