Abstract	Nickel ferrite (Ni x Fe 3-x O 4 ) have been synthesized using solid state reaction with composition (2x)NiO : (3-x)Fe 2 O 3 (x = 0.5; 1.0; 1.5 dan 2.0) in mol in wt% . Mixing of this powder was milled with HEM (High Energy Milling) for 10 hours, and then sintered at 1000 °C for 3 h. X-ray diffraction pattern indicates that the all of samples are single phase in this stage. FTIR (Fourier transform infrared) analysis showed two absorption bands in the range of ~410 - ~600 cm -1 related to octahedral and tetrahedral sites. The magnetic measurement using vibrating sample magnetometer (VSM) shows that the sample exhibited a ferromagnetic behaviour with its coercivity value in the range of 164-217 Oe, and the maximum value wasshowed by x =1.5. VNA ( Vector Network Analyzer ) characterization shows the ability electromagnetic wave absorption with RL (reflection loss) value of -28 dB occurs at frequency of 10.98 GHz. It means that the Ni 1.5 Fe 1.5 O 4 sample can absorb microwave about ~96 % at 10.98 GHz.
