These findings suggest that a 12.5% Mg doping of KCu[F.sub.3] does not alter the fundamental mechanism and the magnitude of the interactions building up the magnetic ordering
of copper spins within the structure.
One topic that has sustained interest over the years, t hough, is the magnetic ordering that occurs in superconductors (4-7), and we will present some examples below.
The effects of magnetic impurities and the possibility of magnetic ordering in superconductors have had a rich and interesting history, and neutrons have played an essential role in determining the nature of the magnetic order since the Meissner screening of the superconducting electrons masks the magnetism from most probes.
Powder diffraction at BT-l was used to elucidate the phase separation, structure, and magnetic ordering
of these compounds.
For magnetic fields in the ab-plane, the different [S.sub.z] levels mix together, the spin gap never closes, and no magnetic ordering
occurs for any field.

of rare earth monochalcogenides.
The orthorhombic structure with a Pnma space group forms the stable crystal structure of ReMn[O.sub.3] perovskite oxides with Re = La to Dy, which belongs to the magnetic ferroelectrics induced by magnetic ordering
The f-electron is associated with the magnetic ordering
having lower energy than conduction electron.
Choi, "Cracks induced by magnetic ordering
in the antiperovskite ZnN[Mn.sub.3], "Physical Review B, vol.
These results open a possibility of producing the porous magnetic matrices and multifunctional nanocomposite materials with coexisting ferroelectric and magnetic orderings
with developed interface based on these porous glasses.
