Laser-written reconfigurable energy landscapes and programmable Moiré spin textures
Matteo Panzeri, Piero Florio, Davide Girardi +18
Magnetic textures are central to emerging spintronic and unconventional computing technologies due to their rich dynamics, topological properties and nanoscale dimensions. A major…
Tuning the coexistence regime of incomplete and tubular skyrmions in ferro/ferri/ferromagnetic trilayers
Oguz Yildirim, Riccardo Tomasello, Yaoxuan Feng +8
The development of skyrmionic devices requires a suitable tuning of material parameters in order to stabilize skyrmions and control their density. It has been demonstrated recently…
Coexistence of distinct skyrmion phases observed in hybrid ferromagnetic/ferrimagnetic multilayers
Andrada-Oana Mandru, Oğuz Yıldırım, Riccardo Tomasello +6
Materials hosting magnetic skyrmions at room temperature could enable new computing architectures as well as compact and energetically efficient magnetic storage such as racetrack…
Performance of synthetic antiferromagnetic racetrack memory: domain wall vs skyrmion
R. Tomasello, V. Puliafito, E. Martinez +4
A storage scheme based on racetrack memory, where the information can be coded in a domain or a skyrmion, seems to be an alternative to conventional hard disk drive for high densit…
Spin-Hall nano-oscillator with oblique magnetization and Dzyaloshinskii-Moriya interaction as generator of skyrmions and nonreciprocal spin-waves
A. Giordano, R. Verba, R. Zivieri +9
Spin-Hall oscillators are promising sources of spin-wave signals for magnonics applications, and can serve as building blocks for magnonic logic in ultralow power computation devic…
Micromagnetic study of electrical-field-assisted magnetization switching in MTJ devices
M. Carpentieri, R. Tomasello, M. Ricci +2
Perpendicular MgO-based Magnetic Tunnel Junctions are optimal candidates as building block of Spin Transfer Torque (STT) magnetoresistive memories. However, up to now, the only STT…
Chirp spectroscopy applied to the characterization of Ferromagnetic Resonance in Magnetic Tunnel Junctions
M. Ricci, P. Burrascano, M. Carpentieri +2
Magnetic Tunnel Junction devices find use in several applications based on the exploitation of the Spin-Transfer Torque phenomenon. The Ferromagnetic Resonance curve is a key chara…
Topological, non topological and instanton droplets driven by spin-transfer torque in materials with perpendicular magnetic anisotropy and Dzyaloshinskii-Moriya Interaction
Mario Carpentieri, Riccardo Tomasello, Roberto Zivieri +1
The interfacial Dzyaloshinskii-Moriya Interaction can modify the topology of droplets excited by a localized spin-polarized current. Here, we show that, in addition to the stationa…
Intrinsic synchronization of an array of spin-torque oscillators driven by the spin-Hall effect
Giulio Siracusano, Riccardo Tomasello, Vito Puliafito +5
This paper micromagnetically studies the magnetization dynamics driven by the spin-Hall effect in a Platinum/Permalloy bi-layer. For a certain field and current range, the excitati…
Dynamical properties of three terminal magnetic tunnel junctions: spintronics meets spin-orbitronics
R. Tomasello, M. Carpentieri, G. Finocchio
This letter introduces a micromagnetic model able to characterize the magnetization dynamics in three terminal magnetic tunnel junctions, where the effects of spin-transfer torque…
