Imaging currents in HgTe quantum wells in the quantum spin Hall regime
Katja C. Nowack, Eric M. Spanton, Matthias Baenninger +10
The quantum spin Hall (QSH) state is a genuinely new state of matter characterized by a non-trivial topology of its band structure. Its key feature is conducting edge channels whos…
Scanning SQUID Susceptometry of a paramagnetic superconductor
J. R. Kirtley, B. Kalisky, J. A. Bert +8
Scanning SQUID susceptometry images the local magnetization and susceptibility of a sample. By accurately modeling the SQUID signal we can determine the physical properties such as…
Behavior of vortices near twin boundaries in underdoped
B. Kalisky, J. R. Kirtley, J. G. Analytis +3
We use scanning SQUID microscopy to investigate the behavior of vortices in the presence of twin boundaries in the pnictide superconductor Ba(Fe1-xCox)2As2. We show that the vortic…
Dynamics of single vortices in grain boundaries: I-V characteristics on the femto-volt scale
B. Kalisky, J. R. Kirtley, E. A. Nowadnick +7
We employed a scanning Hall probe microscope to detect the hopping of individual vortices between pinning sites along grain boundaries in YBCO thin films in the presence of an appl…
