Influence of Ag doping on the dielectric and magnetic properties of LiFe5O8 ceramics

A novel spinel Li1-xAgxFe5O8 (0 <= x < 0.2) method. Based on XRD and SEM analysis, it was found that the spinel solid solution was formed in limited composition range. Both the dielectric and magnetic properties have been improved a lot, and the Li0.95Ag0.05Fe5O8 sample achieved the higher the real part of both permittivity and permeability as 170 and 47.1, respectively at 200 MHz and 20 MHz, which was attributed to the Ag+ substitutions. Considering its dielectric and magnetic properties, the Li1-xAgxFe5O8 (0 <= x <0.2) ceramics provide a way in developing multifunctional materials for multifunctional electronic devices applications.
