Energy-efficient spin Hall nano-oscillators using CoGd ferrimagnets
Jiayu Lei, Raghav Sharma, Shishun Zhao +5
Conventional spin Hall nano-oscillators (SHNOs) based on ferromagnets face practical limitations due to high threshold current densities and large external magnetic field requireme…
Fractional parametric resonance in spintronic diodes
Andrea Grimaldi, Denys Slobodianiuk, Eleonora Raimondo +7
Parametric pumping is a powerful tool for the excitation, amplification, and processing of oscillations and waves of different nature. In general, parametric resonance can occur wh…
A scalable and resource-efficient pipelined p-computer for probabilistic Ising machines
Deborah Volpe, Eleonora Raimondo, Andrea Grimaldi +7
Probabilistic Ising machines (PIMs) based on probabilistic bits offer a hardware-friendly route to solve combinatorial optimization problems, but most digital implementations achie…
Harnessing orbital Hall effect for energy-efficient magnetization switching in room-temperature van der Waals ferromagnet Fe3GaTe2
Chenhui Zhang, Hua Bai, Yuchen Pu +1
2D van der Waals (vdW) magnets provide new opportunities for spin-orbit torque magnetoresistive random-access memory (SOT-MRAM) due to their unique properties. Electrically manipul…
Electrical manipulation and detection of perpendicular altermagnetic order via proximitized Dirac semimetal
Zhaohui Li, Wenqing He, Hua Bai +14
Altermagnets, which combine antiferromagnetic-like magnetic compensation with ferromagnetic-like broken time-reversal symmetry, hold great promise for high-density and ultrafast sp…
A Fourier-Space Approach to Physics-Informed Magnetization Reconstruction from Nitrogen-Vacancy Measurements
Alexander Setescak, Florian Bruckner, Dieter Suess +8
Reconstructing magnetization textures from nitrogen-vacancy (NV) magnetometry stray-field measurements is a challenging, fundamentally ill-posed inverse problem, further complicate…
