Signatures of dephasing by mirror-symmetry breaking in weak-antilocalization magnetoresistance across the topological transition in PbSnSe
Alexander Kazakov, Wojciech Brzezicki, Timo Hyart +12
Many conductors, including recently studied Dirac materials, show saturation of coherence length on decreasing temperature. This surprising phenomenon is assigned to external noise…
Circular and linear magnetic quantum ratchet effects in dual-grating-gate CdTe-based nanostructures
P. Faltermeier, G. V. Budkin, S. Hubmann +9
We report on the observation and systematic study of polarization sensitive magnetic quantum ratchet effects induced by alternating electric fields in the terahertz frequency range…
Magnetic quantum ratchet effect in (Cd,Mn)Te- and CdTe-based quantum well structures with a lateral asymmetric superlattice
P. Faltermeier, G. V. Budkin, J. Unverzagt +13
We report on the observation of magnetic quantum ratchet effect in (Cd,Mn)Te- and CdTe-based quantum well structures with an asymmetric lateral dual grating gate superlattice subje…
Mesoscopic transport in electrostatically-defined spin-full channels in quantum Hall ferromagnets
Aleksandr Kazakov, George Simion, Yuli Lyanda-Geller +5
In this work we use electrostatic control of quantum Hall ferromagnetic transitions in CdMnTe quantum wells to study electron transport through individual domain walls (DWs) induce…
Electrostatic control of quantum Hall ferromagnetic transition, a step toward reconfigurable network of helical channels
Aleksandr Kazakov, George Simion, Yuli Lyanda-Geller +5
Ferromagnetic transitions between quantum Hall states with different polarization at a fixed filling factor can be studied by varying the ratio of cyclotron and Zeeman energies in…
