Abstract

Abstract: 3D magnetic nanostructures are of great interest due to the possibility to design novel properties and the benefits for both technological applications such as high‐density data storage, as well as more fundamental studies. One of the main challenges facing the realization of these three‐dimensional systems is their fabrication, which includes the deposition of magnetic materials on 3D surfaces. In this work, the electroless deposition of Ni–Fe on a 3D‐printed, non‐conductive microstructure is presented. The deposited films exhibit low coercivity, with the saturation magnetization and composition corresponding to the archetypal soft magnetic material permalloy. For fundamental studies of 3D micromagnetism, this new development in fabrication offers the possibility to combine the flexibility of 3D nanofabrication techniques such as two‐photon lithography for the fabrication of 3D scaffolds with a homogeneous soft ferromagnetic thin film, and thus represents an important step toward exploring the rich physics of complex 3D magnetic architectures with tailored properties and the development of advanced applications. Abstract : 3D nanomagnetism is a growing scientific field with exciting opportunities for both new physics, and the potential for advanced applications. Here, the homogeneous deposition of high quality Ni–Fe alloys onto 3D scaffolds via electroless deposition is demonstrated, offering a new route for the realization of 3D magnetic nanostructures and opening the door for their experimental investigation.
