Spin-Orbital Hall Nano-Oscillators using PtCr/NiFe
Utkarsh Shashank, Akash Kumar, Daegeun Jo +11
The orbital Hall effect provides a promising route for generating angular-momentum currents beyond conventional spin Hall physics. PtCr alloys exhibit unusually large current-induc…
Raman scattering of phonon polaritons under nanoscale confinement: the role of structure and environment
George Zograf, Betul Kucukoz, Oleg Kotov +10
Strong light-matter coupling gives rise to polaritons -- quasiparticles that combine both photonic and material characteristics. Here, we show that polar nanocrystals exhibit struc…
Bulk spin-orbit torque-driven spin Hall nano-oscillators using PtBi alloys
Utkarsh Shashank, Akash Kumar, Tahereh Sadat Parvini +7
Spin-orbit-torque-driven auto-oscillations in spin Hall nano-oscillators (SHNOs) offer a transformative pathway toward energy-efficient, nanoscale microwave devices for next-genera…
Correlating synthesis, structure and thermal stability of CuBi nanowires for spintronic applications by electron microscopy and in situ scattering methods
Alejandra Guedeja-Marrón, Henrik Lyder Andersen, Gabriel Sánchez-Santolino +10
Bi-doped copper (Cu1-xBix) nanowires (NWs), promising candidates for spintronic applications due to their potential for a giant spin Hall effect (SHE), were synthesized and their s…
