Abstract
Large area patterned NiFeMo thin films possessing long-range order were fabricated by electrodeposition through a template consisting of a self-assembled close-packed monolayer of polystyrene nanospheres of diameter 390 nm. Unlike many methods, this process generates films possessing both two-dimensional in-plane periodicity and features of varying cross-section in the growth direction. As a consequence, the magnetic properties of the patterned NiFeMo films depend strongly on film thickness. Inhomogeneous magnetization reversal that can be explained by different regions having different effective in-plane coercivities was observed for films with thickness greater than the nanosphere radius, but not for films with lesser thickness. We also observed oscillations in the in-plane coercivity as a function of the film thickness with a period significantly different to that reported for NiFe and Co films prepared by a similar method [A. A. Zhukov et al., Appl. Phys. Lett. 88, 062511 (2006)].
