抄録

The evolution of a two-dimensional labyrinth pattern of magnetic domain structure in a uniaxial garnet thin film is studied. The usually observed domains of the labyrinth structure contain many defects. The labyrinth structure changes to a parallel-stripe structure under magnetic field cycles. In this evolution, defects of the domain pattern disappear. We have introduced a number of magnetic domain junctions as characteristic values of a domain pattern. We have reported that the number of junctions decreases with the power law as a function of the number of ac magnetic field cycles. In this paper, it is found that a one-dimensional correlation function of pattern of magnetic domain structure changes with the number of field cycles as same as the number of junctions decreases.
