Electromagnetic (EM) wave pollution is harmful to human health and environment, thus it absolutely important develop new electromagnetic absorbing materials. MAX phases have been attracted more attention as a potential candidate for materials due their high conductivity nanolaminated structure. Herein, two magnetic with multiprincipal elements ((Ti
MAX phases are highly promising materials for electromagnetic (EM) wave absorption because of their specific combination metal and ceramic properties, making them particularly suitable harsh environments. However, higher matching thickness impedance mismatching can limit ability to attenuate EM waves. To address this issue, researchers have focused on regulating the electronic structure through structural engineering. In study, we successfully synthesized a ternary phase known as Sc2GaC with...
