|Abstract:||The doped lanthanum manganites have unusual magnetic and transport properties, which makes it possible for this material to be used for absorbing microwave. In this study, La0.67Ba0.33Mn0.98TM0.02O3 (TM = Ti and Ni) were prepared by solid state reaction method as microwave absorption material. The crystal structure and magnetic properties were characterized by XRD and permagraph. Refinement results showed both of samples are single phase with monoclinic crystal structure. And hysteresis loops results showed that the La0.67Ba0.33Mn0.98TM0.02O3 (TM = Ti and Ni) samples are soft magnetic materials. Microwave absorption properties were investigated in the frequency range 8-12 GHz using vector network analyzer. An optimal reflection loss of -13 dB is reached at 11.5 GHz for TM = Ti and optimal reflection loss of -6 dB is reached at 11.5 GHz for TM = Ni.|
