Investigation of Co and Ni catalysts effect in carbon nanotubes synthesis and magnetic

Authors

Abstract

Carbon nanotubes (CNT) were synthesized by CVD method based on Ni(NO3)2.6H2O and Co(NO3)2.6H2O solution with two different ratios [Ni/Co = (1/ 0.5) , (1/ 0.0)]. We obtained the magnetic properties of the samples, such as coercivity field, saturate magnetization, retentivity magnetization and magnetic susceptibility by using of the magnetic hysteresis loops. It was found that carbon nano tubes were synthesized by using combination of Ni(NO3)2.6H2O and Co(NO3)2.6H2O catalysts, have much higher coercivity field, but less retentivity magnetization and saturation magnetization compared with the nanotubes were synthesized by using of the only Ni(NO3)2.6H2O catalyst
