Domain wall motion in ferromagnetic nanowires driven by a localized Gaussian thermal gradient

This study uses stochastic Landau-Lifshitz-Gilbert simulations to demonstrate that magnetic domain walls in ferromagnetic nanowires are primarily driven by magnonic spin-transfer torque rather than entropic torque when displaced from a localized Gaussian thermal gradient, revealing how laser parameters and material properties nonlinearly influence wall velocity to guide thermal control in spintronic devices.

Geometric Spin-Orbit Coupling Resolves the Contradictory CISS Effect in Chiral Single Molecules

This paper resolves contradictory experimental findings on the chirality-induced spin selectivity (CISS) effect in single molecules by proposing a theoretical framework where geometric spin-orbit coupling and environmental decoherence interact to produce significant spin polarization specifically in an intermediate-decoherence regime, thereby unifying observations across diverse molecular systems.

What Is the Real-Time Atomistic Mechanism Behind Chirality-Induced Spin Selectivity in Donor-Chiral Bridge-Acceptor Molecules?

This paper proposes a quantum dynamical model revealing that geometric spin-orbit coupling, which is significantly stronger than intrinsic coupling in twisted binaphthyl bridges, serves as the intrinsic mechanism driving high spin polarization in photo-excited donor-chiral bridge-acceptor molecules without requiring external fields.
