Modeling Phase Separation in Polymer-Derived Silicon Carbonitride Ceramics through Extended Machine Learning Molecular Dynamics

Abstract Polymer-derived ceramics combine the thermal stability of ceramics with the versatile properties of carbon domains, but modeling their atomic-scale evolution during processing remains elusive because of the limitations of traditional computational methods. To address thi...

Focused He⁺ Ion Irradiation for Deterministic Nanoscale Domain Wall Pinning and Domain Nucleation in Current-Driven Magnetization Switching

Abstract Predictive domain wall nucleation, propagation, and pinning is achieved by He⁺ ion irradiation of spin-orbit torque thin film devices. Engineering the magnetic anisotropy landscape with nm precision, we demonstrate that non-irradiated gaps as small as 10 nm can act as re...

Yu-Shiba-Rusinov-assisted Andreev transport in a molecular junction between superconductors

Magnetic impurities in superconductors host Yu-Shiba-Rusinov (YSR) bound states, whereas weak superconducting junctions sustain subharmonic charge transport through multiple Andreev reflections (MAR). We explore these phenomena using a molecular-scale junction created by placing...
