Listing Magnetic Spin Directions GSAS
To list the contents of a magnetic unit cell, the following input can be
supplied to program GEOMETRY in the GSAS suite. This program is run in EXPGUI
by selecting the appropriate menu item from the Results menu item.
A sample run of GEOMETRY is shown below. User-typed
input is emphasized by display in this font:
Input.
The amount of output generated by this program can be large, so that it may
be impossible to see all generated information on the terminal window, even
with scrolling. However, all of the generated information is also copied
to the GSAS .LST file, where it can be reviewed with a text editor or
EXPGUI utility LSTVIEW. Note that results from versions of this program
prior to mid-August of 2005 should not be trusted.

Locations and spin directions for all magnetic atoms in the unit cell
Spin vectors are displayed with three different sets of coordinates.
Fractional coordinates have x || a, y || b & z || c with units
of Bohr Magnetron/Angstrom
Input orthogonal coordinates are in Bohr Magnetrons with x || a, y || b*
and z in the a-c plane (z || a x b*)
z||c* orthogonal coordinates are in Bohr Magnetrons with x || a, y in a-b
plane (y || a x c*) and z || c* -- a commonly used orthonormal setting
