Ultra-sensitive voltage-controlled skyrmion-based spintronic diode
Davi Rodrigues, Riccardo Tomasello, Giulio Siracusano +2
We have designed a passive spintronic diode based on a single skyrmion stabilized in a magnetic tunnel junction and studied its dynamics induced by voltage-controlled anisotropy (V…
Role of magnetic skyrmions for the solution of the shortest path problem
Riccardo Tomasello, Anna Giordano, Francesca Garesci +5
Magnetic skyrmions are emerging as key elements of unconventional operations having unique properties such as small size and low current manipulation. In particular, it is possible…
Micromagnetic understanding of the skyrmion Hall angle current dependence in perpendicular magnetized ferromagnets
Riccardo Tomasello, Anna Giordano, Stefano Chiappini +9
The understanding of the dynamical properties of skyrmion is a fundamental aspect for the realization of a competitive skyrmion based technology beyond CMOS. Most of the theoretica…
Chiral skyrmions in an anisotropy gradient driven by spin-Hall effect
Riccardo Tomasello, Stavros Komineas, Giulio Siracusano +2
A strategy to drive skyrmion motion by a combination of an anisotropy gradient and spin Hall effect has recently been demonstrated. Here, we study the fundamental properties of thi…
Observation of Magnetic Radial Vortex Nucleation in a Multilayer Stack with Tunable Anisotropy
Vedat Karakas, Aisha Gokce, Ali Taha Habiboglu +11
Recently discovered exotic magnetic configurations, namely magnetic solitons appearing in the presence of bulk or interfacial Dzyaloshinskii-Moriya Interaction (i-DMI), have excite…
Description of statistical switching in perpendicular STT-MRAM within an analytical and numerical micromagnetic framework
