Oxygen incorporation in YBaCuO thin films: surface activation and degradation
Alexander Stangl, Xavier Obradors, Anna Palau +2
The oxygen off-stoichiometry plays a pivotal role for the physical properties of superconducting oxides. Yet, there is a lack of knowledge on the fundamental processes of oxygen in…
High harmonic spectroscopy of quantum phase transitions in a high-T superconductor
Jordi Alcalà, Utso Bhattacharya, Jens Biegert +9
We report on the new non--linear optical signatures of quantum phase transitions in the high-temperature superconductor YBCO, observed through high harmonic generation. While the l…
Ultra-high critical current densities of superconducting YBaCuO thin films in the overdoped state
A. Stangl, A. Palau, G. Deutscher +2
Doping is one of the most relevant paths to tune the functionality of cuprates, it determines carrier density and the overall physical properties of these impressive superconductin…
Intrinsic Anisotropy and Pinning Anisotropy in Nanostructured YBaCuO from Microwave Measurements
N. Pompeo, A Alimenti, K Torokhtii +9
Anisotropy is an intrinsic factor that dictates the magnetic properties of YBCO, thus with great impact for many applications. Artificial pinning centres are often introduced in an…
Probing the Lattice Anharmonicity of Superconducting YBaCuO Via Phonon Harmonics
Alberto Ramos-Alvarez, Nina Fleischmann, Luciana Vidas +3
We examine coherent phonons in a strongly driven sample of optimally-doped high temperature superconductor YBaCuO. We observe a non-linear lattice response of the 4…
First observation of flux avalanches in a-MoSi superconducting thin films
F. Colauto, M. Motta, A. Palau +3
We have observed the occurrence of dendritic flux avalanches in an amorphous film of MoSi. These events are understood to have a thermomagnetic origin and involve the…
