O.S. Demokritov:
Biquadratic interlayer coupling in layered magnetic systems
Review Article

J. Phys D: Appl. Phys. 31 (1998) 925-941.

An unusual interlayer coupling, recently discovered in layered magnetic
systems, is analysed from the experimental and theoretical points of
view. This coupling favours the 90 degrees orientation of
the magnetization of the adjacent magnetic films. It can be
phenomenologically described by a term in the energy expression, which is
biquadratic with respect to the magnetizations of the two films.  
The main experimental findings, as well as the theoretical models,
explaining the phenomenon are discussed.
