Electronic mechanism of sub-100-fs demagnetization induced by a femtosecond light pulse
Konrad J. Kapcia, Victor Tkachenko, Flavio Capotondi +4
A quantitative understanding of the processes that trigger light-induced demagnetization on ultrashort timescales is crucial for achieving an ultrafast, radiation-controlled magnet…
Phase Separation in Heritage Objects Made of Plasticised PVC: the Case of Joseph Beuys Multiples
Marwa Saad, Sonia Bujok, Aurora Cairoli +9
This work addresses the advanced degradation of plasticised PVC boards, which constitute Joseph Beuys multiples Phosphorus-Cross Sled, focusing on the mechanisms responsible for th…
Magnetocaloric effect in TbCo and DyCo thin films deposited on Si substrates
P. Skokowski, M. Matczak, Ł. Frąckowiak +4
We present the structural, magnetic, and magnetocaloric properties of thin films with stoichiometry TbCo and DyCo deposited on naturally oxidized silico…
Ab initio study of pressure-induced phase transition, band gaps and X-ray photoemission valence band spectra of YVO
M. Werwiński, J. Kaczkowski, P. Leśniak +4
High-pressure induced structural transition from zircon-type phase into scheelite-type phase in YVO is studied using ab initio calculations. Several structures with compressed…
Optical excitation and detection of high-frequency Sezawa modes in Si/SiO2 system decorated with Ni80Fe20 nanodot arrays
Piotr Graczyk, Bivas Rana, Aleksandra Trzaskowska +4
Surface acoustic waves have emerged as one of the potential candidates for the development of next-generation wave-based information and computing technologies. For practical devic…
Migration of phthalate plasticisers in heritage objects made of poly(vinyl chloride): mechanical and environmental aspects
Sonia Bujok, Tomasz Pańczyk, Kosma Szutkowski +4
To clean or not to clean? The solution to this dilemma is related to understanding the plasticiser migration which has a few practical implications for the state of museum artefact…
