Growing a LaAlO3/SrTiO3 heterostructure on Ca2Nb3O10 nanosheets
Alexander J. H. van der Torren, Huiyu Yuan, Zhaoliang Liao +8
The two-dimensional electron liquid which forms between the band insulators LaAlO3 (LAO) and SrTiO3 (STO) is a promising component for oxide electronics, but the requirement of usi…
Conductivity of LaAlO/SrTiO3 Interfaces made by Sputter Deposition
I. M. Dildar, D. B. Boltje, M. H. S. Hesselberth +3
We have investigated the properties of interfaces between LaAlO3 films grown on SrTiO3 substrates singly terminated by TiO2. We used RF sputtering in a high-pressure oxygen atmosph…
Supercurrents through half-metallic ferromagnetic CrO revisited
M. S. Anwar, M. Hesselberth, M. Porcu +1
We report on the observation of a supercurrent through the half metallic ferromagnet CrO grown on hexagonal AlO (sapphire). The current was observed to flow over a dist…
Vortex dynamics in superconducting channels with periodic constrictions
K. Yu, M. B. S. Hesselberth, P. H. Kes +1
Vortices confined to superconducting easy flow channels with periodic constrictions exhibit reversible oscillations in the critical current at which vortices begin moving as the ex…
Superconducting properties of Nb thin films deposited on porous silicon templates
M. Trezza, S. L. Prischepa, C. Cirillo +9
Porous silicon, obtained by electrochemical etching, has been used as a substrate for the growth of nanoperforated Nb thin films. The films, deposited by UHV magnetron sputtering o…
Picovoltmeter for probing vortex dynamics in a single weak-pinning Corbino channel
T. W. Heitmann, K. Yu, C. Song +4
We have developed a picovoltmeter using a Nb dc Superconducting QUantum Interference Device (SQUID) for measuring the flux-flow voltage from a small number of vortices moving throu…
