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…
