X-ray magnetic circular dichroism of altermagnet -FeO based on multiplet ligand-field theory using Wannier orbitals
Ruiwen Xie, Hamza Zerdoumi, Hongbin Zhang
Hematite -FeO is a -wave altermagnetic material, which has an easy-axis phase and easy-plane weak ferromagnetic phase below and above Morin transition temperature, re…
Redox Chemistry of LiCoO, LiNiO, and LiNiMnCoO Cathodes: Deduced via XPS, DFT+DMFT, and Charge Transfer Multiplet Simulations
Ruiwen Xie, Maximilian Mellin, Wolfram Jaegermann +3
Understanding the evolution of the physicochemical bulk properties during the Li deintercalation (charging) process is critical for optimizing battery cathode materials. In this st…
Accelerated Design of Mechanically Hard Magnetically Soft High-entropy Alloys via Multi-objective Bayesian Optimization
Mian Dai, Yixuan Zhang, Weijia He +7
Designing high-entropy alloys (HEAs) that are both mechanically hard and possess soft magnetic properties is inherently challenging, as a trade-off is needed for mechanical and mag…
Optimizing -FeN as permanent magnet via alloying
Bo Zhao, Ruiwen Xie, Imants Dirba +3
Based on systematic first-principles calculations, we investigate the effects of 27 alloying elements on the intrinsic magnetic properties of FeN, in order to further op…
