  The superexchange interaction



Time: 1:30pm, March 19 (Thursday)

Title: The superexchange interaction

Speaker: Prof. Chong-Der Hu
   (Dept. of Physics, National Taiwan Univ.)

Place: Information Building 2F CS247


The superexchange interaction between magnetic ions is studied.
We will discuss its mechanism first, then we generalize it to the situation that
there are more than one orbitals in each ion. The anisotropy of orbitals
played an important role on hybridization. Thus the superexchange
interaction is closely related to orbital ordering. Finally, we will show
the effective form of the superexchange interaction and its application to manganites.
