Lorenzo Poggini,Giuseppe Cucinotta,Abdul-Muizz Pradipto,Marco Scarrozza,Paolo Barone,Andrea Caneschi,Patrizio Graziosi,Marco Calbucci,Raimondo Cecchini,Valentin Dediu,Silvia Picozzi,Matteo Mannini,Roberta Sessoli +12 more
TL;DR: In this paper, a self-assembling monolayer technique has been used to chemisorb a paramagnetic phosphonate functionalized nitronyl-nitroxide radical (NitPO) on the ferromagnetic La 0.7Sr0.3MnO3 (LSMO) manganite surface.
Journal ArticleDOI
Oxygen Impurities Link Bistability and Magnetoresistance in Organic Spin Valves
Ilaria Bergenti,Francesco Borgatti,Marco Calbucci,Alberto Riminucci,Raimondo Cecchini,Patrizio Graziosi,Donald A. MacLaren,Angelo Giglia,Jean-Pascal Rueff,Denis Céolin,Luca Pasquali,Luca Pasquali,Valentin Dediu +12 more
TL;DR: Variable oxygen doping of the organic molecules represents the key element for correlating bistability and MR, and the measurements provide the first experimental evidence in favor of the impurity-driven model describing the spin transport in organic semiconductors in similar devices.
Journal ArticleDOI
Study of the magnetic microstructure of Ni/NiO nanogranular samples above the electric percolation threshold by magnetoresistance measurements
TL;DR: It is concluded that in the sample with lower Ni content neither the physical percolation of the Ni nanocrystallite/matrix interface exchange energy term nor the magnetic percolations are achieved, and in the other sample physicalPercolation is reached while magnetic perColation is still absent.
