“…Electrodeposition may be used as a fabrication methodology, but it is not as straight forward as for fabricating NWs. Therefore, modified routes of electrodeposition and various other approaches have been used to grow NTs of pure metals and alloys [40,[45][46][47][48][49][50][51][52][53] Arrays of Ni NTs were fabricated in track-etched 21 μm thick PC membranes with pore diameter (D) of 150 nm and packing density (P) of 6 %. They were fabricated using a two-step procedure as depicted in Fig.…”

Reprinted with permission from [36] reversal properties of ferromagnetic NTs were investigated experimentally as a function of their geometrical parameters by other magnetometry techniques [9,15,25,45,46,50,65]. In multisegmented nanocylinders, with alternating magnetic wires and tubes segments, it was shown that the NT segments switch their magnetization before the NWs resulting in a trapped domain wall between the two segments [51].…”

The fundamental properties of 2D arrays of magnetic nanowires and nanotubes (NWs and NTs) have been well described theoretically, but real systems are subject to certain flaws and imperfections which strongly affect the mechanism and dynamics of magnetization reversal. Therefore, before exploiting the vast potential of magnetic NWs and NTs, there is a need to investigate the materials parameters as well as the field dependent magnetic properties in real systems. Amongst the various issues at stake for a comprehensive understanding of these arrays is the influence of long-range dipolar interactions because these interactions strongly influence the magnetization reversal and thus the switching field distributions (SFD) which plays a significant role for information storage. Particularly, the width of the SFD is important since smaller values of this parameter leads to less recording errors and it is also a measure of the quality of the recording media. Consequently, the understanding a

“…Several authors have reported a simple method to study the magnetization reversal modes in NTs by combining experimental measurements and analytical calculations of the angular dependence of coercivity (Ahmad et al, 2011a;Chen et al, 2013;Escrig et al, 2007aEscrig et al, , 2008aLiu et al, 2009;Proenca et al, 2013b;Rozman et al, 2011;Shamaila et al, 2009;Sharif et al, 2008Sharif et al, , 2013Sui et al, 2004). Stoner and Wohlfarth (1991) have reported the angular dependence of the nucleation field for a coherent magnetization reversal:…”

“…Various synthesis methods have been employed for production of these alloys; including high vacuum sputtering [13], pulsed laser deposition [14], epitaxial vapor deposition [8], floating zone [15] and electrodeposition [4][5][6][7][16][17][18][19][20][21][22]. Not only electrodeposition process is favorable from the economical point of view, but also it brings the possibility of controlling chemical composition [7,16,20].…”

In this work, Fe-Pd alloy films have been electrodeposited on different substrates using an electrolyte containing [Pd(NH 3) 4 ] 2 + (0.02 M) and [Fe-Citrate] 2 + (0.2 M). The influences of substrate and overpotential on chemical composition, nucleation and growth kinetics as well as the electrodeposited films morphology have been investigated using energy dispersive X-ray spectroscopy (EDS), current-time transients, scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD) patterns. In all substrates-brass, copper and sputtered fluorine doped tin oxide on glass (FTO/glass)-Fe content of the electrodeposited alloys increases by increasing the overpotential. Also the cathodic current efficiency is low due to high rate of H 2 co-reduction. Regarding the chronoamperometry current-time transients, it has been demonstrated that the nucleation mechanism is instantaneous with a typical three dimensional (3D) diffusion-controlled growth in the case of brass and copper substrates; while for FTO, the growth mode changes to 3D progressive. At a constant overpotential, the calculated number of active nucleation sites for metallic substrates is much higher than that of FTO/glass; however by increasing the overpotential, the number of active nucleation sites increases. The SEM micrographs as well as the XRD patterns reveal the formation of Fe-Pd alloy thin films with nanostructure arrangement and ultrafine grains.
