Ongoing effects of pandemic-imposed learning disruption on student attitudes
Teemu Hynninen, Henna Pesonen, Olli Lintu +1
We present a study on the development of Finnish first-year physics majors' attitudes towards physics, as measured by the Colorado Learning Attitudes about Science Survey, before,…
Proton irradiation effects on metal-YBCO interfaces
C. Acha, G. A. Sanca, M. Barella +6
10 MeV proton-irradiation effects on a YBCO-based test structure were analyzed by measuring its current-voltage (IV) characteristics for different cumulated fluences. For fluences…
YBCO-based non-volatile ReRAM tested in Low Earth Orbit
C. Acha, M. Barella, G. A. Sanca +5
An YBCO-based test structure corresponding to the family of ReRAM devices associated with the valence change mechanism is presented. We have characterized its electrical response p…
Electrical conduction mechanisms of metal / high-Tc superconductor (YBCO) interfaces
L. F. Lanosa, H. Huhtinen, P. Paturi +1
Current-voltage characteristics of Au~/~YBaCuO interfaces (Au/YBCO), built on optimally-doped YBCO thin films, grown by pulsed laser deposition, were measured as a…
First-principles investigations of the magnetic phase diagram of GdCaMnO
Hichem Ben Hamed, Martin Hoffmann, Waheed A. Adeagbo +5
We studied for the first time the magnetic phase diagram of the rare-earth manganites series GdCaMnO (GCMO) over the full concentration range based on density f…
Tuning the probability of defect formation via substrate strains in SrFeMoO films
Waheed A. Adeagbo, Martin Hoffmann, Arthur Ernst +4
Since oxide materials like SrFeMoO are usually applied as thin films, we studied the effect of biaxial strain, resulting from the substrate, on the electronic and magnetic…
Absence of broken time reversal symmetry beneath the surface of YBCO films
H. Saadaoui, Z. Salman, T. Prokscha +4
We report the results of a search for spontaneous magnetism due to a time reversal symmetry breaking phase in the superconducting state of (110)-oriented YBCO films, expected near…
Giant vortex states in type I superconductors simulated by Ginzburg-Landau equations
Heikki Palonen, Juha Jäykkä, Petriina Paturi
The quantization of magnetic flux in superconductors is usually seen as vortices penetrating the sample. While vortices are unstable in bulk type I superconductors, restricting the…
Electrical anisotropy of heteroepitaxial InSb/GaAs layers
T. A. Komissarova, A. N. Semenov, D. A. Kirilenko +5
We report on study of electrical and structural properties of InSb/GaAs(001) heteroepitaxial layers in [110] and [1-10] crystallographic directions. Strong anisotropy of electron t…
Modelling reduced field dependence of in YBCO films with nanorods
Heikki Palonen, Juha Jäykkä, Petriina Paturi
Flux pinning is still the main limiting factor for the critical current of the high-temperature superconductors in high fields. In this paper we model the field dependence of the c…
