As the interest in magnetic excitations continues to grow, and user-friendly tools enable more researchers to model inelastic neutron scattering data, the need for a database that catalogues the published spin-wave spectra and the associated effective spin Hamiltonians became evident. Deciphering the origin of spin wave excitations provides a detailed understanding of the origins of magnetic phenomena in ordered materials, which is of great importance to achieving scientifical and technological advances.

The intent of the Spin Wave Information Catalog (SWIC) is to provide sufficient information to reconstruct any reported spin-wave spectrum measured on powder or single crystal materials using inelastic neutron scattering. The SWIC is using Structured Query Language (SQL) and Oracle's APEX to allow users to easily navigate the database via the webpage, and search the entries based on fields such as: chemical composition, the nature of magnetic orders, magnetic atoms, type of exchange parameters, quantum spin value, authors, facilities, neutron spectrometers, and much more. The spin-waves in this database are described using one or both of two popular spin-wave modeling software packages: SpinW and Su(n)ny Suite, which can be downloaded at these links:

We need your help expanding this database to include more published spin wave systems. With a large catalog of spectra entries, the modeling of inelastic neutron scattering data can be streamlined significantly by readily accessing information about spin dynamics in similar materials and providing starting fitting models. Furthermore, by leveraging the database, machine learning algorithms could be developed to accelerate the discovery of novel exotic magnetic materials. Users willing to propose new entries should send the SpinW or Sunny files to garleao@ornl.gov together with the reference article that describes the spin-wave model. A brief guideline for describing the proposed spin-wave entry can be downloaded here.
