High-entropy oxides (HEOs) leverage extreme chemical disorder to achieve unique and tunable properties. In this talk, we explore how structural and functional behavior in HEOs can be tailored by varying composition and synthesis conditions. Focusing on spinel systems, we show that magnetic transitions, structural phases, and other behaviors can be systematically tuned in a high entropy system. Polycrystalline powders and thin films are synthesized and characterized using a range of techniques, including magnetometry, X-ray diffraction, X-ray spectroscopy, and electron microscopy. We highlight how atomic-scale disorder leads to meaningful changes in performance and demonstrate how entropy-driven design offers new pathways for tuning properties. These findings expand our understanding of disorder–property relationships and point to promising applications in sensing, magnetics, and energy systems. |
