摘要：
The structural states of the discrete 2D XY model with dipole and exchange interactions are studied numerically. It is shown that the ground state passes through a sequence of transitions of staircase type with increasing exchange constant. For small values of the exchange the constant ground state is continually degenerate. Metastable chaotic structures are shown to exist. (C) 1997 Published by Elsevier Science B.V.
