Magnetic small-angle neutron scattering – from nanoscale magnetism to long-range magnetic structures
Edited by Sabrina Disch, Sebastian Mühlbauer, Andreas Michels and Elliot Paul Gilbert
This virtual special issue of Journal of Applied Crystallography brings together 16 articles representing the cutting-edge work of around 80 individual co-authors; it showcases the breadth of magnetic SANS across the full gamut of magnetic nanostructures and identifies recent and future trends, as well as instrumentation capabilities and novel simulation tools.

A virtual special issue of Journal of Applied Crystallography brings together a series of articles on magnetic small-angle neutron scattering, with the aim of raising awareness of the range of science cases that can be addressed with the technique and exploring future challenges related to magnetic SANS theory and data analysis. It is also hoped that this special issue will encourage collaborations between communities working on long-range-ordered magnetic textures and nanoscale magnetism.
The anisotropic fractal magnetic domain structure in bulk single-crystal (Fe0.63Ni0.30Pd0.07)3P has been quantitatively characterized using small-angle neutron scattering.

In the frustrated chiral magnet Co6.75Zn6.75Mn6.5, small-angle neutron scattering reveals that the mesoscale chiral magnetism displays strong disorder and the skyrmion phase is nearly entirely suppressed.

This article reviews the opportunities and limitations of time-involved small-angle neutron scattering experiments, with the typical artifacts of the recorded data illustrated by virtue of the response of the skyrmion lattice in MnSi under periodic changes of the direction of the stabilizing field.
The vortex lattice phase diagram, order and transition kinetics in superconducting MgB2 doped with either manganese or carbon were studied using small-angle neutron scattering.

A method is presented for extracting quantitative information on superconducting vortex lattices and other mesoscopic structures from time-of-flight small-angle neutron scattering.
Spin-wave scattering in amorphous ferromagnets has been measured by the method of small-angle scattering of polarized neutrons. The method is shown to allow the determination of the spin-wave stiffness of such systems and an inherent energy gap that demonstrates nonconstant behaviour with increasing applied magnetic field.
The application of neutron scattering to the study of metallic reentrant spin glasses is reviewed through a series of experimental results. In particular, the role of small-angle neutron scattering is highlighted. A few lines of work which could be pursued thanks to recent developments of the technique are suggested.

Characteristics of irradiation-induced nanofeatures derived from magnetic small-angle neutron scattering are reported for low-dose neutron-irradiated Fe–(5–14)Cr–NiSiP model alloys and the reduced-activation ferritic/martensitic 9Cr steel Eurofer97.

Based on the continuum theory of micromagnetics, theoretical expressions for the polarization of the scattered neutron beam in uniaxial small-angle neutron scattering have been derived and their predictions tested by analyzing experimental data on a soft magnetic nanocrystalline alloy. The here-presented theoretical framework forms the basis for polarized real-space methods such as spin-echo small-angle neutron scattering, spin-echo modulated small-angle neutron scattering and polarized neutron dark-field contrast imaging.

Small-angle neutron scattering and small-angle X-ray scattering are important experimental techniques for studying the behaviour and properties of materials on the nanoscale. This article describes a numerical algorithm that uses reverse Monte Carlo simulations to model scattering intensities observed on a two-dimensional small-angle scattering detector.
