"Spin exchange interactions and magnetic properties"

Mike Whangbo , NC State University
[Host: Seunghun Lee]
This talk will briefly review how the spin exchange interactions of magnetic solids are described quantitatively and qualitatively. When the choice of a spin lattice is made by inspecting the geometrical pattern of the magnetic ion arrangement or by seeking the novelty of the physics the chosen model generates, interesting but erroneous interpretations often result. The importance of choosing a spin lattice on the basis of electronic structure considerations is emphasized. The magnetic solids to be discussed in this talk include: Cs 2 CuCl 4 , Na 3 Cu 2 SbO 6 , Bi 4 Cu 3 V 2 O 14 , Cu 3 (CO 3 ) 2 (OH) 2 , AgCrO 2 , Ca 3 CoMnO 6 , MnWO 4 , [Cu(HF 2 )(pyz) 2 ]BF 4 .
