Fermin, R. (author), Scheinowitz, N. M.A. (author), Aarts, J. (author), Lahabi, K. (author)With the ever-increasing energy need to process big data, the realization of low-power computing technologies, such as superconducting logic and memories, has become a pressing issue. Developing fast and nonvolatile superconducting memory elements, however, remains a challenge. Superconductor-ferromagnet hybrid devices offer a promising...journal article 2022

Dildar, I.M. (author), Neklyudova, M. (author), Xu, Q. (author), Zandbergen, H.W. (author), Harkema, S. (author), Boltje, D. (author), Aarts, J. (author)Sputter deposition of oxide materials in a high-pressure oxygen atmosphere is a well-known technique to produce thin films of perovskite oxides in particular. Also interfaces can be fabricated, which we demonstrated recently by growing LaAlO3 on SrTiO3 substrates and showing that the interface showed the same high degree of epitaxy and atomic...journal article 2015

Non-conducting interfaces of LaAlO3/SrTiO3 produced in sputter deposition: The role of stoichiometryDildar, I.M. (author), Boltje, D.B. (author), Hesselberth, M.H.S. (author), Aarts, J. (author), Xu, Q. (author), Zandbergen, H.W. (author), Harkema, S. (author)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 atmosphere. The films are smooth, with flat surfaces. Transmission electron microscopy shows sharp and continuous interfaces with some slight intermixing. The elemental ratio...journal article 2013

Anwar, M.S. (author), Czeschka, F. (author), Hesselberth, M. (author), Porcu, M. (author), Aarts, J. (author)We report on measurements of supercurrents through the half-metallic ferromagnet CrO2 grown on hexagonal Al2O3 (sapphire). The current was observed to flow over a distance of 700 nm between two superconducting amorphous Mo70Ge30 electrodes which were deposited on the CrO2 film. The critical current Ic increases as function of decreasing...journal article 2010

Yang, Z.Q. (author), Zhang, Y.Q. (author), Aarts, J. (author), Wu, M.Y. (author), Zandbergen, H.W. (author)We report the effects of biaxial strain on the charge ordering temperature Tco of the mixed-valent manganite perovskite oxide Pr0.5Ca0.5MnO3. Thin films were grown on SrTiO3, which has a 1.3% larger in-plane lattice parameter. Other substrates were used for comparison. Transport measurements combined with data from electron microscopy show that...journal article 2006
