Abstract
AbstractNanometric AgFeO2 and AgCrO2 delafossite were easily prepared by the flash auto-combustion method. The two main bands estimated from FTIR (Fourier-transform infrared) analysis were the tetrahedral A-site (573 cm−1 for AgFeO2, 630 cm−1 for AgCrO2) and the octahedral B-site (484 cm−1 for AgFeO2, 595 cm−1 for AgCrO2). This study is mainly focused on the elastic properties evaluated from the FTIR analysis and showed that AgCrO2 delafossite is more elastic than AgFeO2 delafossite. The elastic properties can be explained by studying the longitudinal and transverse velocities. Owing to the optical properties results, AgCrO2 delafossite is a promising material to be applied in optical devices. However, AgFeO2 delafossite is a promising material in magnetic applications because it showed a large switching field distribution by 9-fold more than that of AgCrO2 delafossite. Moreover, high-frequency applications were calculated from the magnetic analysis and showed that both samples could be applied in ultra-high microwave applications.
