Hydrostatic pressure response of an oxide two-dimensional electron system
J. Zabaleta, V. S. Borisov, R. Wanke +10
Two-dimensional electron systems with fascinating properties exist in multilayers of standard semiconductors, on helium surfaces, and in oxides. Compared to the two-dimensional (2D…
Emerging magnetism and electronic phase separation at titanate interfaces
N. Pavlenko, T. Kopp, J. Mannhart
The emergence of magnetism in otherwise nonmagnetic compounds and its underlying mechanisms have become the subject of intense research. Here we demonstrate that the nonmagnetic ox…
Direct k-space mapping of the electronic structure in an oxide-oxide interface
G. Berner, M. Sing, H. Fujiwara +11
The interface between LaAlO3 and SrTiO3 hosts a two-dimensional electron system of itinerant carriers, although both oxides are band insulators. Interface ferromagnetism coexisting…
Magnetically ordered state at correlated oxide interfaces: the role of random oxygen defects
Natalia Pavlenko, Thilo Kopp
Using an effective one-band Hubbard model with disorder, we consider magnetic states of the correlated oxide interfaces, where effective hole self-doping and a magnetially ordered…
Oxygen vacancies at titanate interfaces: two-dimensional magnetism and orbital reconstruction
N. Pavlenko, T. Kopp, E. Y. Tsymbal +2
We show that oxygen vacancies at titanate interfaces induce a complex multiorbital reconstruction which involves a lowering of the local symmetry and an inversion of t2g and eg orb…
Magnetism and superconductivity at LAO/STO-interfaces: the role of Ti 3d interface electrons
N. Pavlenko, T. Kopp, E. Y. Tsymbal +2
Ferromagnetism and superconductivity are in most cases adverse. However, recent experiments reveal that they coexist at interfaces of LaAlO3 and SrTiO3. We analyze the magnetic sta…
