Stabilization of zigzag order in NiPS via positive biquadratic interaction
Qiang Luo, Shuhang Yang, Xiaoying Wang +4
Despite extensive research, the precise spin Hamiltonian of the van der Waals antiferromagnet NiPS -- which hosts a zigzag-ordered ground state -- remains debated. While consen…
Bio-resorbable magnetic tunnel junctions
Dong-Jun Kim, Beom Jin Kim, Hee-Chang Shin +7
Magnetic tunnel junctions (MTJs) play a crucial role in spintronic applications, particularly data storage and sensors. Especially as a non-volatile memory, MTJs have received subs…
Securing generative artificial intelligence with parallel magnetic tunnel junction true randomness
Youwei Bao, Shuhan Yang, Hyunsoo Yang
Deterministic pseudo random number generators (PRNGs) used in generative artificial intelligence (GAI) models produce predictable patterns vulnerable to exploitation by attackers.…
250 Magnetic Tunnel Junctions-Based Probabilistic Ising Machine
Shuhan Yang, Andrea Grimaldi, Youwei Bao +4
In combinatorial optimization, probabilistic Ising machines (PIMs) have gained significant attention for their acceleration of Monte Carlo sampling with the potential to reduce tim…
Chiral damping of magnons
Dae-Yun Kim, Imane Berrai, T. S. Suraj +11
Chiral magnets have garnered significant interest due to the emergence of unique phenomena prohibited in inversion-symmetric magnets. While the equilibrium characteristics of chira…
