Keywords： nanotube arrays

CuFe2O4 nanotube arrays with different outer diameters were synthesized in anodic aluminum oxide templates through sol-gel techniques followed by heating treatment processes.The morphology of the nanotube arrays was investigated by field emission scanning electron microscope and transmission electron microscopy,suggesting that the nanotube arrays are ordered and uniform.The X-ray diffraction results indicate that the crystal structure of the nanotube arrays is polycrystalline with a spinel-type structure.The measurements of magnetic properties indicate that CuFe2O4 nanotube arrays with outer diameter of 200 nm exhibit magnetic anisotropy with easy magnetization direction along the axis of nanotubes.
