Double exchange interaction

Along with the electronic interactions (double exchange, HDVV exchange, etc.) the coupling of electronic and vibrational motions (vibronic coupling) plays a crucial role in MV systems. One of the main characteristics of MV compounds is the... [Pg.565]

Schematically, the double exchange interaction can be written in the form of a spin Hamiltonian operator (working on the system spin AB —for short, S) as...

The fact that LSMO is ferromagnetic in the charge-ordered, insulating state is remarkable, since it indicates that the ferromagnetic interaction at low temperatures cannot arise from the double exchange mechanism. We note here that other... [Pg.569]
