Giant Effective Permeability in Drude Thin Films Probed by THz Time-Domain Spectroscopy
Gian Paolo Papari, Zahra Mazaheri, Antonio Vettoliere +7
The electromagnetic response of metallic films is commonly analyzed in terahertz spectroscopy by assuming unit relative magnetic permeability. In this work we show that this assump…
Tailoring defects and nanocrystal transformation for optimal heating power in bimagnetic particles
George Antonaropoulos, Marianna Vasilakaki, Kalliopi N. Trohidou +5
The effects of cobalt incorporation in spherical heterostructured iron oxide nanocrystals (NCs) of sub-critical size have been explored by colloidal chemistry methods. Synchrotron…
Inverse magnetic hysteresis of the Josephson supercurrent: study of the magnetic properties of thin niobium/permalloy (Fe_{20}Ni_{80}) interfaces
Roberta Satariano, Loredana Parlato, Antonio Vettoliere +12
We propose a picture for the magnetic properties of superconductor/ferromagnet (S/F) heterostructures based on Nb and permalloy (Py: Fe_{20}Ni_{80}). By measuring the magnetic mome…
Vacancy-driven non-cubic local structure and magnetic anisotropy tailoring in FeO-FeO nanocrystals
Alexandros Lappas, George Antonaropoulos, Konstantinos Brintakis +8
In contrast to bulk materials, nanoscale crystal growth is critically influenced by size- and shape-dependent properties. However, it is challenging to decipher how stoichiometry,…
Critical influence of target-to-substrate distance on conductive properties of LaGaO3/SrTiO3 interfaces deposited at 10-1 mbar oxygen pressure
Carmela Aruta, Salvarore Amoruso, Giovanni Ausanio +8
We investigate pulsed laser deposition of LaGaO3/SrTiO3 at 10-1 mbar oxygen background pressure, demonstrating the critical effect of the target-to-substrate distance, dTS, on the…
Improved structural ordering in sexithiophene thick films grown on single crystal oxide substrates
Carmela Aruta, Pasquale D'Angelo, Mario Barra +2
We report on sexithiophene films, about 150nm thick, grown by thermal evaporation on single crystal oxides and, as comparison, on Si/SiO2. By heating the entire deposition chamber…
