摘要：

We have studied the spin waves in square and rectangular dots by Brillouin light scattering. The effects of the demagnetizing field are investigated and commented. In square dots, the observed fourfold symmetry configurational in-plane anisotropy is qualitatively interpreted as resulting from the non-homogeneous profile of the static magnetization, (C) 2002 Elsevier Science B.V.
