    17271727are summed to give the total that is measured in a magnetic powder diffraction
    17281728experiment. This allows us to model the structure as two separate crystalline
    1729 phases; one consists of the chemical arrangement of all the atoms in the
    1730 crystal structure described with a conventional unit cell and space group, and
     1729phases; one consists of the arrangement of all the atoms in the
     1730crystal structure described with a conventional unit cell and space
     1731group (the chemical or sometimes "nuclear" structure), and
    17311732the other contains only the magnetic atoms in a perhaps different unit cell
    17321733with a magnetic space group to describe the atom and magnetic moment
    1733 arrangement. Needless to say both phases must describe the same atomic
    1734 arrangement for the magnetic ions; these will be linked as needed by
    1735 constraints in order to maintain this arrangement.</p>

     1735Needless to say the magnetic ions only have one set of positions,
     1736both phases must describe the same atomic

     1738constraints between the phases in order to maintain this arrangement.</p>
