The magnetic behavior of low-dimensional materials has attractedconsiderable attention in the fields of sensors, energy storage, catalysis,and wastewater treatment [1]. Among the top-down approaches used toproduce such structures, direct laser interference patterning (DLIP) is apowerful method that allows the fabrication of surface structures with goodoutput and scalability [2]. In this work, we present a study on the shapedependentmagnetic anisotropy of periodic arrays of nickel microwires(MWs) prepared with a variety of geometries and micrometric precision,while enabling the efficient use of a two-beam laser interferenceconfiguration of the Direct Laser Interference Patterning technique (DLIP)[3] on sputter-deposited Ni thin films.
