Two-dimensional electron system at the magnetically tunable EuO/SrTiO interface
Patrick Lömker, Tobias C. Rödel, Timm Gerber +6
We create a two-dimensional electron system (2DES) at the interface between EuO, a ferromagnetic insulator, and SrTiO3, a transparent non-magnetic insulator considered the bedrock…
Frequency and wavenumber selective excitation of spin waves through coherent energy transfer from elastic waves
Yusuke Hashimoto, Davide Bossini, Tom H. Johansen +3
Using spin-wave tomography (SWaT), we have investigated the excitation and the propagation dynamics of optically-excited magnetoelastic waves, i.e. hybridized modes of spin waves a…
Electron spin dynamics of Ce ions in YAG crystals studied by pulse-EPR and pump-probe Faraday rotation
D. V. Azamat, V. V. Belykh, D. R. Yakovlev +6
The spin relaxation dynamics of Ce ions in heavily cerium-doped YAG crystals is studied using pulse-electron paramagnetic resonance and time-resolved pump-probe Faraday rota…
Rydberg excitons in the presence of an ultralow-density electron-hole plasma
J. Heckötter, M. Freitag, D. Fröhlich +7
We use two-color pump-probe spectroscopy to study Rydberg excitons in CuO in the presence of free carriers injected by above-band-gap excitation. Already at plasma densities $ρ…
Experimental evidence for a second hydrogen ordered phase of ice VI
Tobias M. Gasser, Alexander Thoeny, Lucie Plaga +4
In the last decade five new ice phases were experimentally prepared. Two of them are empty clathrate hydrates and three of them represent hydrogen ordered counterparts of previousl…
Long-range p-d exchange interaction in a ferromagnet-semiconductor Co/CdMgTe/CdTe quantum well hybrid structure
I. A. Akimov, M. Salewski, I. V. Kalitukha +14
The exchange interaction between magnetic ions and charge carriers in semiconductors is considered as prime tool for spin control. Here, we solve a long-standing problem by uniquel…
Nuclear spin cooling by helicity-alternated optical pumping at weak magnetic fields in -GaAs
P. S. Sokolov, M. Yu. Petrov, K. V. Kavokin +8
The spin dynamics of localized donor-bound electrons interacting with the nuclear spin ensemble in -doped GaAs epilayers is studied using nuclear spin polarization by light with…
Scaling laws of Rydberg excitons
J. Heckötter, M. Freitag, D. Fröhlich +4
Rydberg atoms have attracted considerable interest due to their huge interaction among each other and with external fields. They demonstrate characteristic scaling laws in dependen…
Transient photon echoes from donor-bound excitons in ZnO epitaxial layers
S. V. Poltavtsev, A. N. Kosarev, I. A. Akimov +8
The coherent optical response from 140~nm and 65~nm thick ZnO epitaxial layers is studied using transient four-wave-mixing spectroscopy with picosecond temporal resolution. Resonan…
Dynamics of exciton magnetic polarons in CdMnSe/CdMgSe quantum wells: the effect of self-localization
I. A. Akimov, T. Godde, K. V. Kavokin +7
We study the exciton magnetic polaron (EMP) formation in (Cd,Mn)Se/(Cd,Mg)Se diluted-magnetic-semiconductor quantum wells using time-resolved photoluminescence (PL). The magnetic f…
High resolution two-dimensional optical spectroscopy of electron spins
M. Salewski, S. V. Poltavtsev, I. A. Yugova +7
Multidimensional coherent optical spectroscopy is one of the most powerful tools for investigating complex quantum mechanical systems. While it was conceived decades ago in magneti…
