摘要：

The results of complex investigations of the crystalline structure, composition and specific magnetization of the multi-wall carbon nanotubes (CNTs) filled by magnetic nanocomposite are performed. CNT arrays have been synthesized by the high temperature pyrolysis of fluid hydrocarbon -p-xylole [C8H10] in the presence of volatile catalyst -ferrocene [Fe(C5H5)(2)] at the walls of tubular-type quartz reactor of specially constructed equipment. It was revealed that the obtained CNTs constitute complex nanocomposite: C - Fe3C - Fe5C2 - Fe. The magnetic properties of such CNTs in the temperature region of 78 <= T <= 1060 K are conditioned by the ferric carbide (in the form Fe3C H Fe5C2) and Fe.
