TetMaG-Guided Design and Operando Electron Holography Validation of Current-Induced Domain-Wall Motion in 3D Curved and Cornered Fe Nanobridges

This study combines TetMaG micromagnetic simulations, FEBID fabrication, and operando electron holography to demonstrate that 3D curved and cornered Fe nanobridges exhibit distinct, geometry-dependent domain-wall behaviors, where corners act as pinning sites while curves enable smooth motion, with experimental results validating the predicted magnetic configurations and current-induced switching.

Direct observation of interfacial exchange coupling in a magnetic tunnel junction through spin-polarized quasiparticle interference

Using spin-polarized scanning tunneling microscopy and quasiparticle interference, researchers directly observed and characterized the interfacial exchange coupling in a magnetic tunnel junction, revealing how a ferromagnetic tip induces a significant, tunable energy shift in the surface states of a Cr(001) substrate that is sensitive to tip distance and magnetic alignment.

Inter-band coherence effects in disordered crystals: beyond the non-crossing approximation

This paper develops a quantum kinetic theory for Bloch electrons that extends beyond the non-crossing approximation by including fourth-order impurity scattering to capture extrinsic, disorder-strength-independent contributions to anomalous transport phenomena, which are demonstrated through analytical results for the anomalous Hall conductivity in a two-dimensional massive Dirac fermion model.

Interplay of Electrode Coupling Engineering, Quasiperiodicity, and Magnetic Flux in Quantum Transport through a Su-Schrieffer-Heeger Ring

This study demonstrates that engineering electrode-coupling configurations, particularly through asymmetric multi-site reservoirs, can fundamentally reshape coherent charge and heat transport in magnetic-flux-threaded quasiperiodic Su-Schrieffer-Heeger rings by inducing disorder-assisted conducting phases and enabling precise control over transport regimes through the interplay of topology, quasiperiodicity, and quantum interference.

Kinetics of electron-phonon scattering in silicon resolved by Rydberg transitions of donors

By combining a comprehensive theoretical model of donor-phonon kinetics with time-resolved free electron laser measurements, this study resolves the kinetics of electron-phonon scattering in silicon to demonstrate that the conduction band minimum is located further from the X-point than commonly assumed, thereby establishing donor relaxation as a precision metrology for silicon band parameters.

Synchronic scattering and geometric dephasing in microwave-induced resistance oscillations

This paper presents a novel quantum transport model for microwave-induced resistance oscillations that attributes net direct current generation to velocity-modulated scattering rates breaking time-reversal symmetry and explains amplitude saturation at high intensities through a non-linear geometric dephasing mechanism triggered when the oscillation amplitude approaches the cyclotron radius.

Real-space identification of distinct magnetic configurations in a candidate d-wave altermagnet

By employing spin-polarized scanning tunneling microscopy and magnetic-field-dependent quasiparticle interference imaging, this study resolves the magnetic origin of momentum-dependent spin splitting in the candidate d-wave altermagnet KV2Se2O by identifying coexisting C-type and G-type magnetic configurations and establishing a direct link between real-space magnetic order and momentum-space electronic signatures.
