Influence of annealing on the microwave-absorption properties of(NiCo)/TiO_2 nanocomposites

XU Zhi-jie;DU Bao-sheng;DU Sheng-jie;LIU Feng;ZHAO Mei-xing;SUN Nai-kun;School of Science,Shenyang Ligong University;  
(NiCo)/TiO2nanocomposites composed of tetragonal TiO2(rutile)and cubic NiCo were prepared by ball milling in Ar atmosphere and then annealed at 500 ℃for 0.5h.The phase structure,morphology,the magnetic properties and the electromagnetism parameters of the(NiCo)/TiO2nanocomposites were examined by X-ray diffraction,scanning electron microscope,vibrating sample magnetometer and vector net work analyzer. Compared with the as-milled samples,the Bragg reflections of NiCo for the annealed sample are clearly narrowed,suggesting a larger grain size and a smaller microstrain,leading to an increase of saturation magnetization intensity,and a decrease of coercive force.The samples show the behavior of dielectric relaxation and magnetic resonance,and annealing optimizes the microstructure,which leads to significant strengthen of interface polarization and polarization loss in frequency range 12-16GHz,while the optimal reflection loss decrease from-6.4to-14.8dB for 8mm thickness.After annealing the nature resonance peaks at 2.6,5.3GHz,and the exchange resonance peaks at 10.5,13,15.6GHz are greatly enhanced.
