Mesoporous eskolaite, Cr 2 O 3 prepared by using the evaporation method with mesoporous KIT-6 silica as a hard template has been analysed with SQUID magnetometry and variable temperature neutron powder diffraction (NPD). NPD analysis shows that the magnetic and crystallographic properties of the eskolaite structure within the walls of the mesoporous Cr 2 O 3 material are identical to that of “bulk” material, R 3 ¯ c . The refined magnetic moments on the Cr 3 + ions are lower than observed for bulk material due to the higher proportion of surface atoms, creating local disorder. This is corroborated by the magnetometry results, which suggest a small amount of ferromagnetism may be present at low temperatures.
