Abstract:

The problem of stability of various ferromagnetic and antiferromagnetic spin configurations is considered. Simple cubic, face-centered cubic, and body-centered cubic lattices are analyzed, for all possible ratios of the strengths of the nearest-neighbor and next-nearestneighbor exchange constants all other exchange constants are neglected, and for all temperatures. The calculations are carried out by a Green function random phase approximation. The results are presented in terms of phase diagrams, and the nature of the instabilities at the phase boundaries is discussed. Author
