Nowadays we need material that can reduce electromagnetic interference (EMI). Doped LaMnO3 has electromagnetic properties which makes it possible for this material to be used for microwave absorption material. In this study the Ni doped (Ni=0.05) La0.67Sr0.33MnO3 was fabricated by sol-gel method and characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy-Electron Energy Dispersive Spectroscopy (SEM-EDS), and Vector Network Analyzer (VNA). The XRD result showed that the material was single phase and the crystal structure of the material was rhombohedral with space group R-3c. The lattice parameter of sample decreased after incorporation of Ni. The influence incorporation of Ni into LSMO on microwave absorption performance was investigated. The microwave absorption performance was improved after Ni doping. The maximum reflection loss was -6.29 dB at 11.47 GHz.
