Abstract
Abstract High‐entropy (HE) oxides have become increasingly popular as electromagnetic wave‐absorbing materials owing to their customizable structure and unique HE effects. However, the weak loss property of single‐phase HE ceramics and the approaches implemented to improve them based on semi‐empirical rules severely limit their development. Herein, two biphasic HE oxides are prepared by simple sintering to realize accurate regulation of crystal phases and structural defects. It is verified that HE effects cause various defects that are beneficial for microwave dissipation within complex‐phase ceramics. In spinel/perovskite HE oxides, around the interface of spinel (111) and perovskite (110) planes, notable…
