Infrared nanoscopy down to liquid helium temperatures
D. Lang, J. Döring, T. Nörenberg +7
We introduce a scattering-type scanning near-field infrared microscope (s-SNIM) for the local scale near- field sample analysis and spectroscopy from room (RT) down to liquid heliu…
Towards diluted magnetism in TaAs
Yu Liu, Zhilin Li, Liwei Guo +10
Magnetism in Weyl semimetals is desired to investigate the interaction between the magnetic moments and Weyl fermions, e.g. to explore anomalous quantum Hall phenomena. Here we dem…
Interplay between localization and magnetism in (Ga,Mn)As and (In,Mn)As
Ye Yuan, Chi Xu, René Hübner +6
Ion implantation of Mn combined with pulsed laser melting is employed to obtain two representative compounds of dilute ferromagnetic semiconductors (DFSs): Ga1-xMnxAs and In1-xMnxA…
Ultrafast Carrier Dynamics in VO across the Pressure-Induced Insulator-to-Metal Transition
Johannes M. Braun, Harald Schneider, Manfred Helm +5
We utilize near-infrared pump and mid-infrared probe spectroscopy to investigate the ultrafast electronic response of pressurized VO. Distinct pump-probe signals and a pumping…
Interaction between magnetic moments and itinerant carriers in d0 ferromagnetic SiC
Yu Liu, Ye Yuan, Fang Liu +12
Elucidating the interaction between magnetic moments and itinerant carriers is an important step to spintronic applications. Here, we investigate magnetic and transport properties…
Doubly dressed bosons - exciton-polaritons in a strong terahertz field
B. Piętka, N. Bobrovska, D. Stephan +12
We demonstrate the existence of a novel quasiparticle: an exciton in a semiconductor doubly dressed with two photons of different wavelengths: near infrared cavity photon and terah…
