Anisotropic magnetic interactions and spin dynamics in the spin-chain compound Cu(py)Br: An experimental and theoretical study
J. Zeisner, M. Brockmann, S. Zimmermann +9
We compare theoretical results for electron spin resonance (ESR) properties of the Heisenberg-Ising Hamiltonian with ESR experiments on the quasi-one-dimensional magnet Cu(py)B…
Spin dynamics and magnetic interactions of Mn dopants in the topological insulator BiTe
S. Zimmermann, F. Steckel, C. Hess +5
The magnetic and electronic properties of the magnetically doped topological insulator BiMnTe were studied using electron spin resonance (ESR) and measure…
Preferential antiferromagnetic coupling of vacancies in graphene on SiO_2: Electron spin resonance and scanning tunneling spectroscopy
S. Just, S. Zimmermann, V. Kataev +3
Monolayer graphene grown by chemical vapor deposition and transferred to SiO_2 is used to introduce vacancies by Ar^+ ion bombardment at a kinetic energy of 50 eV. The density of d…
Cluster-induced crater formation
Christian Anders, Gerolf Ziegenhain, Steffen Zimmermann +1
Using molecular-dynamics simulation, we study the crater volumes induced by energetic impacts ( km/s) of projectiles containing up to N=1000 atoms. We find that for Lenn…
Lateral superlattices as voltage-controlled traps for excitons
S. Zimmermann, A. O. Govorov, W. Hansen +3
We demonstrate the localisation of quantum well excitons in a periodic array of linear traps using photoluminescence experiments. The excitonic traps are induced by applying spatia…
Acoustically driven storage of light in a quantum well
C. Rocke, S. Zimmermann, A. Wixforth +3
The strong piezoelectric fields accompanying a surface acoustic wave on a semiconductor quantum well structure are employed to dissociate optically generated excitons and efficient…
