3D Neutron Microscopy

This week we highlight a paper in Nature Physics by Nikolay Kardjilov and co-authors “Three-dimensional imaging of magnetic fields with polarized neutrons”. 3D tomography and microscopy with x-rays is nothing new. Neutrons, however, provide the advantage of strong scattering from … Continue reading
