DOI 10.1002/pssb.201900319
Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Fe nanotubes (NTs) are successfully fabricated into the pores of polyethylene terephthalate (PET) ion‐track membranes by potentiostatic electrochemical deposition technique at different voltages. Morphological peculiarities and main structural parameters at different deposition modes are analyzed. NTs have a body‐centered cubic (BCC) lattice with spatial singony Im‐3m(229) typical for the iron phase and selected crystalline direction [110] along the main axis of the 1D nanostructure (NS). The possibility of changing the NT wall thickness by changing the deposition potential is shown. Micro‐ and macromagnetic characteristics of Fe NTs are analyzed and their relationship with morphological and structural features is discussed. The inner diameter, structural and magnetic characteristics of NSs may be simply modulated by controlling the deposition conditions. The results provide a useful method for fabricating low‐cost and a simply scalable route for the design of both separate 1D hollow metal NSs and 2D anisotropic ferromagnetic structural materials on the base of flexible polymer film, which are important for applications in modern nanoelectronics.
