A modified sol-gel method was introduced by employing a cost effective novel template to synthesize coaxial one dimensional (1-D) composite nanostructures based on CoFe{sub 2}O{sub 4} (CFO) - K{sub 0.5}Na{sub 0.5}NbO{sub 3} (KNN) and magnetic nanostructures based on CoFe{sub 2}O{sub 4} (CFO). The studies with scanning electron microscopy (SEM) and atomic force microscopy (AFM) revealed that the composite material is characterized by the 1-D tubular structure. The absorption edge is blue shifted for both KNN and CFO nanotubes due to the lattice strain effect.
