Optical probing of magnons and phonons in Ni80Fe20 nanodot arrays
A. Adhikari, P. Graczyk, A. K. Chaurasiya +3
Control of collective spin excitations by static or dynamic strain is an emerging phenomenon that requires in-depth understanding for design of future spin-wave-regulated devices.…
Hybrid structure with a ferromagnetic film and an array of magnetic molecules for deep-nanoscale reprogrammable magnonics
Oleksandr Pastukh, Piotr Graczyk, Mateusz Zelent +2
Miniaturization is an essential element in the development of information processing technologies and is also one of the main determinants of the usability of the tested artificial…
A Unified Framework for Pattern Recovery in Penalized and Thresholded Estimation and its Geometry
Piotr Graczyk, Ulrike Schneider, Tomasz Skalski +1
We consider the framework of penalized estimation where the penalty term is given by a real-valued polyhedral gauge, which encompasses methods such as LASSO, generalized LASSO, SLO…
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…
