Magnetic nanowire arrays in anodic alumina membranes: Rutherford backscattering characterization

Coercive field behavior of permalloy antidot arrays based on self-assembled template fabrication

“…Vavassori et al [3] have found that on permalloy antidot arrays with characteristic sizes on the micrometer range, the anisotropy of the arrays is clearly related to the antidot lattice symmetry. In our case, as is well known, the hexagonal order degree depends on the first anodization time [6]. For longer first anodization process the pores in the NAM are better ordered.…”

“…The NAMs were fabricated using the so-called two-step anodization process [6] membranes show a porous diameter of 35 nm and have a distance between them of 105 nm, which can be modified by a heat treatment in phosphoric acid (5% in volume) at 35 1C. Such treatment increases the porous diameter in a rate of 2 nm/min of acid etching, keeping fixed the interporous distance [1].…”

Ordered magnetic nanohole and antidot arrays prepared through replication from anodic alumina templates

“…NAM templates have been fabricated using the so-called two-step anodization process using oxalic acid as anodization bath [8][9][10][11][12][13]. Time of first anodization process ranged between 3 and 72 h [14] resulting in increasing the size of domain regions where pores arrange into perfect hexagonal symmetry.…”

Influence of electrodeposition techniques on Ni nanostructures

“…Vasquez and coworkers prepared Ni nanowires by electrodeposition inside AAM pores and found that the magnetic behaviour changes with the aspect ratio (length to width ratio) of nanowires [26][27][28][29][30]. Other authors reported that preferential plane of nanowires growth is dependent on AAM pore diameter; therefore, the magnetic behaviour can be controlled through this parameter [31,32].…”
