“…In this fashion, complete magnetization in the direction of the applied field (magnetic saturation) will take place at higher magnetic fields compared to the case of continuous films 63,64,[289][290][291] . Further control over the magnetic behavior was achieved by the engineering of the diameter of the holes and the edge to edge distance between holes by tailoring the alumina template (w) [292][293][294] . Moreover, there has been reported an inversion of the magnetization easy axis from the in-plane direction (along the film) to the out of plane direction above a certain hole diameter (with an improvement of the magnetic performance in the perpendicular direction).…”

“…Anodized aluminum oxide (AAO) has been under study for several decades, leading to the optimization of obtaining highly ordered and tunable nanostructures in terms of diameter. This makes AAO a promising material as templates for the fabrication of functional materials with reduced dimensionality [8][9][10][11][12]. The successful development of an anodization-based process to generate nanotube arrays has extended from aluminum to other metallic or intermetallic materials, such as titanium oxide [13].…”

The study investigates the impact of the electrolyte composition and anodization conditions on titanium oxide microstructures, analyzing their influence on a trilayer titanium/copper/titanium system. The electrolytes used for anodization had different concentrations of ammonium fluoride and water. The quality and stability of the oxide growth were controlled by monitoring changes in the current density curves during anodization. In water-rich electrolytes, the titanium oxide layer exhibits improved structural quality but reduced layer conductivity, leading to electrical breakdown and destruction of the layer through rapid electrical discharge. Under equilibrium conditions between fluoride ions and water, scanning electron microscope images demonstrate nanoporous structures with inner pore diameters exhibiting a log-normal distribution, with median sizes ranging from 15 to 70 nm across voltage ranges. Linear correlations between the inner pore diameters and the applied voltage are observed, notably in certain electrolytes, indicating stable processes and high quality of the nanopatterned oxide.

“…Any further distribution of this work must maintain attribution to the author(s) and the title of the work, journal citation and DOI. hard to replicate using techniques like nanosphere litography [24] or surface anodization [25] where the structures are well oredered within structural domains which, in turn, may be misaligned with each other. This property of the laser patterning, the excellent geometrical pattern arrangement, is essential for the investigations of the shape-dependent magnetic anisotropy investigations where the external magnetic field is applied parallel to the structurized surface.…”

Magnetic anisotropy in the exchange-biased laser-patterned thin Co/CoO films

Materials exhibiting an exchange bias eﬀect are a class of magnetic systems that have a wide range of possible technological applications e.g. in sensors, read heads, and spintronic devices. In this study, we demonstrate the eﬀect of laser interference patterning on the magnetic properties of Pd/CoO/Co/Pd multilayers. Laser patterning creates arrays of well-ordered stripes, rectangles, and squares on the substrate surface. We found that the laser treatment caused magnetic softening of the structure edges while the centers of the objects remained unchanged and exhibited the exchange bias eﬀect. In this study we focused on the shape and conﬁgurational magnetic anisotropies induced by patterning and showed that the magnetic properties varied depending on the angle at which the external magnetic ﬁeld was applied with respect to the pattern geometry.
