High‐Entropy Enhanced Microwave Attenuation in Titanate Perovskites

High‐Entropy Enhanced Microwave Attenuation in Titanate Perovskites Abstract High‐entropy oxides (HEOs), which incorporate multiple‐principal cations into single‐phase crystals and interact with diverse metal ions, extend the border for available compositions and unprecedented properties. Herein, a high‐entropy‐stabilized (Ca 0.2 Sr 0.2 Ba 0.2 La 0.2 Pb 0.2 )TiO 3 perovskite is reported, and the effective absorption bandwidth (90% absorption) improves almost two times than that of BaTiO 3 . The...
