  Magnetic susceptibility measurements are often the first characterization
tool that researchers turn to when beginning to assess the magnetic nature of a
newly discovered material. Breakthroughs in instrumentation have made the
collection of high quality magnetic susceptibility data more accessible than
ever before. However, the analysis of susceptibility data remains a common
challenge for newcomers to the field of magnetism. While a comprehensive
treatment of the theoretical aspects of magnetism are found in numerous
excellent textbooks, there is a gap at the point of practical application. We
were inspired by this obstacle to put together this guide to the analysis and
interpretation of magnetic susceptibility data, with an emphasis on materials
that exhibit Curie-Weiss paramagnetism.
