Minority-Spin Impurity Band in n-Type (In,Fe)As: A Materials Perspective for Ferromagnetic Semiconductors
Masaki Kobayashi, Le Duc Anh, Jan Minar +9
Fully understanding the properties of n-type ferromagnetic semiconductors (FMSs), complementary to the mainstream p-type ones, is a challenging goal in semiconductor spintronics be…
Vectorial spin-polarization detection in multichannel spin-resolved photoemission spectroscopy using an Ir(001) imaging spin filter
Erik D. Schaefer, Stephan Borek, Jürgen Braun +5
We report on spin- and angular resolved photoemission spectroscopy using a high-resolution imaging spin filter based on a large Ir(001) crystal enhancing the effective figure of me…
Determination of surface and interface magnetic properties for the multiferroic heterostructure Co/BaTiO3 using SPLEED and ARPES
St. Borek, J. Braun, J. Minar +4
Co/BaTiO(001) is one of the most interesting multiferroic heterostructures as it combines different ferroic phases, setting this way the fundamentals for innovative technical a…
Non-magnetic ground state of Ni adatoms on Te-terminated bismuth chalcogenide topological insulators
M. Vondracek, J. Honolka, L. Cornils +20
We report on the quenching of single Ni adatom moments on Te-terminated Bi2Te2Se and Bi2Te3 topological insulator surfaces. The effect becomes manifested as a missing X-ray magneti…
Energetic, spatial and momentum character of a buried interface: the two-dimensional electron gas between two metal oxides
S. Nemšák, G. Conti, A. X. Gray +32
The interfaces between two condensed phases often exhibit emergent physical properties that can lead to new physics and novel device applications, and are the subject of intense st…
Multiferroic heterostructures for spin filter application - an ab initio study
Stephan Borek, Jürgen Braun, Hubert Ebert +1
Novel imaging spin-filter techniques, which are based on low energy electron diffraction, are currently of high scientific interest. To improve the spin-detection efficiency a vari…
Temperature dependent determination of electron heat capacity and electron-phonon factor for FeCrNi
Jan Winter, Jürgen Sotrop, Stephan Borek +2
A theoretical approach using ab initio calculations has been applied to study the interaction of an ultra-short laser pulse with the metal alloy FeCrNi (A…
Study of electronic and magnetic properties and related x-ray absorption spectroscopy of ultrathin Co films on BaTiO
M. Hoffmann, St. Borek, I. V. Maznichenko +7
We present a first-principles study of electronic and magnetic properties of thin Co films on a BaTiO(001) single crystal. The crystalline structure of 1, 2, and 3 monolayer th…
