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…
Direct imaging of the coexistence of ferromagnetism and superconductivity at the LaAlO3/SrTiO3 interface
J. A. Bert, B. Kalisky, C. Bell +4
LaAlO3 and SrTiO3 are insulating, nonmagnetic oxides, yet the interface between them exhibits a two-dimensional electron system with high electron mobility,1 superconductivity at l…
Local measurement of the superfluid density in the pnictide superconductor Ba(FeCo)As across the superconducting dome
Lan Luan, Thomas M. Lippman, Clifford W. Hicks +6
We measure the penetration depth in Ba(FeCo)As using local techniques that do not average over the sample. The superfluid density $ρ_s(T)\equiv1/λ…
Fluxoid fluctuations in mesoscopic superconducting rings
Julie A. Bert, Nicholas C. Koshnick, Hendrik Bluhm +1
Rings are a model system for studying phase coherence in one dimension. Superconducting rings have states with uniform phase windings that are integer multiples of 2 called flux…
