Electrochemistry is a method, which can be used for the creation of nanomaterials. This method has big advantages concerning the reduced restrictions for shape and size of the samples. Furthermore it does not need expensive equipment for sample preparation.

In the paper the preparation of Ni, Co and Fe nanowires is presented. The diameter and length of the obtained nanowires can be tuned by the properties of the template porous material and the time of deposition, respectively. The quality of the nanowires depends also on the deposition mode (AC - alternating current or DC - constant current) and pH of the solution.

The anodization conducted in phosphoric acid allowed to obtain anodic alumina oxide (AAO) with the smallest pore diameter of about 40 nm. Usage of oxalic acid brings the largest pores of around 120 nm. The deposited material inside the pores has the diameter of the templates. The length can be as large as the thickness of the oxide and reaches up to 1 μm. The morphology of the wires was studied by atomic force microscopy (AFM) and electron scanning microscopy (SEM). The wires show a magnetization direction along the main axis. The magnetic characterization was done by magnetic force microscopy (MFM) and Mossbauer spectroscopy.
