Features of obtaining by the method of matrix synthesis, structure and magnetic properties of iron nanowires

Abstract

Nanowires from iron were investigated. Samples in the form of arrays of parallel threads (wires) were obtained by matrix synthesis using track membranes. Matrices with parallel pores of 100 nm were used, and the growth voltage was varied --- 0.8 V, 1 V and 1.2 V. Electron microscopic studies of the growth matrix and samples were carried out. The obtained data of Mossbauer spectroscopy and magnetometry correlate well. Thus, a comparison of the results obtained by these methods showed that with an increase in the deposition potential during the synthesis of nanowires, the misorientation angle of the magnetic moments of domains increases. It is also shown that as the deposition potential increases, the coercive force decreases. Keywords: magnetic nanowires, matrix synthesis, structure, Mossbauer spectroscopy, magnetic properties.
