Crystal structure and magnetism in MnSb2O6: Incommensurate long-range order

MnSb2O6 was investigated by neutron diffraction and magnetic susceptibility techniques. The structure was trigonal, space group P321, a = 8.8011(3) Å, c = 4.7241(1)Å. Low-temperature neutron data gave no evidence of structural change down to 14 K. Inverse susceptibility data show a deviation from Curie-Weiss behavior below 200 K and the magnetization shows a maximum at 12 K associated with the onset of three-dimensional order. A Curie-Weiss law …
