The Workshop on Advanced Nanomagnetism Characterization will be held on August 30th and 31st, 2018, at the Brazilian Center for Research in Energy and Materials (CNPEM) in Campinas, São Paulo. The event will bring together specialists on advanced characterization techniques for obtaining information about magnetism at the nanoscale using a wide variety of probes, such as neutrons, electromagnetic radiation, ions and others. The workshop is also aimed at techniques that could complement the magnetic information, such as the characterization of crystalline and electronic structure. This is a satellite workshop to the 16th International Conference on Molecule-based Magnets.
