Journal ArticleDOI
Skyrmion based microwave detectors and harvesting
Giovanni Finocchio,Marco Ricci,Riccardo Tomasello,Anna Giordano,Marco Lanuzza,Vito Puliafito,Pietro Burrascano,Bruno Azzerboni,Mario Carpentieri +8 more
TL;DR: In this article, a magnetic tunnel junction based spin-transfer torque diode with a magnetic skyrmion as ground state and a perpendicular polarizer patterned as nano-contact was proposed for a local injection of the current.
Journal ArticleDOI
Origin of temperature and field dependence of magnetic skyrmion size in ultrathin nanodots
Riccardo Tomasello,Konstantin Y. Guslienko,Konstantin Y. Guslienko,Marco Ricci,Anna Giordano,Joseph Barker,Mario Carpentieri,Oksana Chubykalo-Fesenko,Giovanni Finocchio +8 more
TL;DR: In this paper, a universal model based on the micromagnetic formalism was proposed to study skyrmion stability as a function of magnetic field and temperature, and it was shown that magnetic skyrms with a small radius are always metastable.
Journal ArticleDOI
Magnetic Radial Vortex Stabilization and Efficient Manipulation Driven by the Dzyaloshinskii-Moriya Interaction and Spin-Transfer Torque.
Giulio Siracusano,Riccardo Tomasello,Anna Giordano,Vito Puliafito,Bruno Azzerboni,Ozhan Ozatay,Mario Carpentieri,Giovanni Finocchio +7 more
TL;DR: This work shows how the interfacial Dzyaloshinskii-Moriya Interaction (IDMI) is able to lift the energy degeneracy of a magnetic vortex state by stabilizing a topological soliton with radial chirality, hereafter called radial vortex.
Journal ArticleDOI
Semi-implicit integration scheme for Landau–Lifshitz–Gilbert-Slonczewski equation
TL;DR: This paper shows how to implement a semi-implicit algorithm based on the Adams-Bashforth algorithm as a predictor, and a second order Adams-Moulton procedure as a corrector in the Landau–Lifshitz–Gilbert-Slonczewski equation.
