Derivative-free tree optimization for complex systems
Ye Wei, Bo Peng, Ruiwen Xie +5
A tremendous range of design tasks in materials, physics, and biology can be formulated as finding the optimum of an objective function depending on many parameters without knowing…
Bayesian optimization with active learning of Ta-Nb-Hf-Zr-Ti system for spin transport properties
Ruiwen Xie, Yixuan Zhang, Fu Li +2
Designing materials with enhanced spin charge conversion, i.e., with high spin Hall conductivity (SHC) and low longitudinal electric conductivity (hence large spin Hall angle (SHA)…
Element-Specific Study of Magnetic Anisotropy and Hardening in SmCoCu Thin Films
Georgia Gkouzia, Damian Günzing, Ruiwen Xie +10
This work investigates the effect of copper substitution on the magnetic properties of SmCo thin films synthesized by molecular beam epitaxy. A series of thin films with vary…
High-throughput screening of Half-antiperovskites with a stacked kagome lattice
Harish K. Singh, Amit Sehrawat, Chen Shen +4
Half-antiperovskites (HAPs) are a class of materials consisting of stacked kagome lattices and thus host exotic magnetic and electronic states. We perform high-throughput calculati…
