Science and Technology of 3D Magnetic Nanostructures

Over many decades, research on magnetic materials has focused on two dimensions, leading to a wealth of new physics, and technological applications. Advances in nanofabrication have enabled the realization of sub-micron geometries leading to numerous scientifically interesting novel spin textures that are governed by topology or frustration, sometimes mimicking those found in bulk materials. Developments in characterization techniques allow now insights into magnetic materials down to fundamental magnetic length and time scales with high sensitivity and selectivity of individual components. The increase in computational capabilities has further opened a path to predict, simulate and interpret the experimental efforts in this field.

Recently, the focus has shifted towards artificial three-dimensional magnetic systems that derive from the accomplishments in lower dimensions. In this Special Topic of APL Materials, we invite authors to submit research in the developing field of 3D nanomagnetism, with its scope covering fundamental phenomena occurring in 3D nanomagnetic systems, materials advances and challenges, and potential technological applications, including devices. This issue will yield a treasure chest of valuable research pieces for the magnetism community and beyond.
