“…At room temperature, the magnetocrystalline anisotropy constant of bulk hcp cobalt was determined to be K 1 = 5.0 × 10 6 erg/cm 3 , while the shape anisotropy of magnetic nanowires was reported to be K s = π M 2 s = 6.10 6 erg/cm 3 [21]. From both the basic and applied research perspectives, a clear understanding of the effects of synthesis parameters (e.g., deposition current and time, pH solution) [22,23,24,25,26,27] and morphology (e.g., wire length and diameter) [6,9,28,29] on the magnetic properties of ordered nanowire arrays is essential. Despite some previous efforts [16,17], effects of the wire diameter on the magnetic properties of the ordered CoNiP nanowire arrays remained to be investigated.…”

Ordered CoNiP nanowires with the same length of 4 µm and varying diameters (d = 100 nm–600 nm) were fabricated by electrodeposition of CoNiP onto polycarbonate templates. X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscopy confirmed the quality of the fabricated nanowires. Magnetic measurements and theoretical analysis revealed that the magnetization reversal and magnetic anisotropy were significantly influenced by varying of the diameters of the nanowires. There existed a critical wire diameter (dc ≈ 276 nm), below which the magnetization reversal occurred via a coherent rotation mode, and above which the magnetization reversal occurred via a curling rotation mode. The easy axis of the magnetization tended to change in direction from parallel to perpendicular with respect to the wire axis as the wire diameter exceeded dc ≈ 276 nm. With increasing wire diameter, the coercive field (Hc) and the remanent to saturation magnetization ratio (Mr/Ms) were also found to rapidly decrease in the range d = 100–400 nm and gradually decrease for d > 400 nm.

“…Moreover, it can allow the alloy composition to be tuned by selectively adjusting the electrodeposition voltage from the same electrochemical bath. Therefore, it has been widely used for growing iron, cobalt, and nickel magnetic nanowires and their alloys (Atalay et al, 2009;Karaagac et al, 2010;Vega et al, 2012a;Liu et al, 2013) with tuned compositions. Furthermore, by pulsing the deposition potential between adequate values, cobalt/copper, cobalt-nickel/copper, and cobalt-platinum/platinum multilayered nanowires have also been reported in the literature (Piraux et al, 1994;Fert and Piraux, 1999;Peng et al, 2007).…”

“…To synthesis one-dimensional nanomaterials by the combination of the sol-gel process and AAO template has been an excellent route recently [21][22][23]. Nanowires and nanotubes have been attractive nanostructured materials for applications in electronic, magnetic, optoelectronic, and sensor due to their unique properties [1,2,24,25]. The synthesize of YBCO nanowires is a challenging subject.…”
