摘要：
Some interesting physical effects are predicted for diluted magnetic semiconductors. It is shown that the spin properties of zinc-blende-type A(II)B(VI) diluted magnetic semiconductors depend crucially on the electronic configuration of the transition-metal ions. Depending on the filling of the ionic d shell, the kinetic exchange Hamiltonian evolves from antiferromagnetic to ferromagnetic Kondo-like form via more complicated forms sensitive to Jahn-Teller distortions.
