Enhanced magnetic frustration in a new high entropy diamond lattice spinel oxide

High‐entropy stabilization chemistry offers a new paradigm in the design of functional materials stabilized by the high configurational entropy. In the present work, a new high entropy spinel material with composition (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)Al2O4 is introduced, detailed structural and microstructural characterizations highlight that the material crystallizes in a cubic spinel structure with an excellent chemical homogeneity at the nanoscale. Magnetic studies show that the frustration (magnetic) parameter (f =│θCW│/TM> 27) is significantly enhanced in this new diamond lattice spinel material.
