Abstract

The development of modern spintronics materials ushered the need for novel characterization tools capable of characterizing nanometer-sized spin textures. Neutrons are a convenient probe for this task due to their angstrom-sized wavelengths, electric neutrality and robustly controllable spin state. Recent research has focused on enabling access to new degrees of freedom in order to provide a neutron toolbox capable of characterizing emerging materials. This includes the development of tomography techniques for characterizing the 3D bulk spin textures and the techniques for creating neutron helical and skyrmion-like spin-orbit states. Here we provide a concise overview of this work and discuss future prospects and applications.
