Compositional disorder in high entropy oxides offers a novel approach to tuning functional properties, yet its impact on magnetic ordering in double perovskite systems remains underexplored. Here, the authors investigate high-entropy rare-earth double perovskite films, revealing robust ferromagnetic ordering and reentrant spin-glass behavior, highlighting the importance of microscopic interactions in low-temperature phases.
