[Pw_forum] spin orbital structure in crystal

[yumin qian]

  My dear friends
    Since the interplay of spin ,orbital ,charge and lattice is a important
topic in strongly correlated system.
    spin ordering and orbital ordering is prevalent in transitional metal
compounds , to illustrate these ordering by figures give us a vivid
understanding or the ordering parameter .
    Is there anyone konw how to draw a picture of spin or d orbit
orientation on a crystal lattice .
    Is there any tool that can be used.
   Many thanks .
