“…Tuning the magnetic anisotropy can be achieved via a series of different preparation methods and conditions. Morpho-structural aspects and structured topography obtained for example by ion beam etching and wet chemical etching [6], oblique deposition [8][9][10] or applying a magnetic field during deposition [11], can be exploited with the purpose to pattern the magnetic material. External control of magnetic anisotropy, coercivity, or magnetic relaxation/superparamagnetism can be achieved via the application of an electric field [12,13].…”

The manipulation of magnetic anisotropy represents the fundamental prerequisite for the application of magnetic materials. Here we present the vectorial magnetic properties of nanostructured systems and thin films of Fe and FeCo prepared on linearly trenched Mo templates with thermally controlled periodicity. The magnetic properties of the nanosystems are engineered by tuning the shape, size, thickness, and composition parameters of the thin films. Thus, we control coercivity, magnetization, orientation of the easy axis of magnetization, and the long-range magnetic order of the system in the function of the temperature. We distinguish magnetic components that emerge from the complex morpho-structural features of the undulating Fe or FeCo nanostructured films on trenched Mo templates: (i) assembly of magnetic nanowires and (ii) assembly of magnetic islands/clusters. Uniaxial anisotropy at room temperature was proven, characterized, and explained in the case of all systems. Our work contributes to the understanding of magnetic properties necessary for possible further applications of linear systems and undulated thin films.

“…Recently, several new methods for manipulation of the magnetic anisotropy are emerging, for instance, (i) magnetic anisotropy control by the obliquely underlayer deposition, (ii) topography, and (iii) application of an external electric field . One additional possibility to tune the magnetic properties is the application of strain fields, which is present in many prominent applications, such as the enhancement of ferroelectricity in BaTiO 3 thin films, controlling the magneto-optical response of BiFeO 3 , generating spin-currents in quantum spin Hall systems, and the electric field survey exchange bias in a Co 90 Fe 10 /BiFeO 3 /SrRuO 3 /PMN-PT heterostructure under different tensile regimes .…”

Tuning the magnetic properties of materials is a demand of several technologies; however, our microscopic understanding of the process that drives the enhancement of those properties is still unsatisfactory. In this work, we combined experimental and theoretical techniques to investigate the handling of magnetic properties of FeCo thin films via the thickness-tuning of a gold film used as an underlayer. We grow the samples by the deposition of polycrystalline FeCo thin films on the Au underlayer at room temperature by a magnetron sputtering technique, demonstrating that the lattice parameter of the sub-20 nm thickness gold underlayer is dependent on its thickness, inducing a stress up to 3% in sub-5 nm FeCo thin films deposited over it. Thus, elastic-driven variations for the in-plane magnetic anisotropy energy, K u , up to 110% are found from our experiments. Our experimental findings are in excellent agreement with ab initio quantum chemistry calculations based on density functional theory, which helps to build up an atomistic understanding of the effects that take place in the tuning of the magnetic properties addressed in this work. The handling mechanism reported here should be applied to other magnetic films deposited on different metallic underlayers, opening possibilities for large-scale fabrication of magnetic components to be used in future devices.
