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…
Agreement between local and global measurements of the London penetration depth
Thomas M. Lippman, Beena Kalisky, Hyunsoo Kim +5
Recent measurements of the superconducting penetration depth in Ba(Fe_1-x Co_x)2As2 appeared to disagree on the magnitude and curvature of Δλ_{ab}(T), even near optimal doping. The…
Measurements of the gate tuned superfluid density in superconducting LaAlO3/SrTiO3
Julie A. Bert, Katja C. Nowack, Beena Kalisky +8
The interface between the insulating oxides LaAlO3 and SrTiO3 exhibits a superconducting two-dimensional electron system that can be modulated by a gate voltage. While gating of th…
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…
Critical thickness for ferromagnetism in LaAlO3/SrTiO3 heterostructures
Beena Kalisky, Julie A. Bert, Brannon B. Klopfer +6
In heterostructures of LaAlO3 (LAO) and SrTiO3 (STO), two nonmagnetic insulators, various forms of magnetism have been observed [1-7], which may [8, 9] or may not [10] arise from i…
