Abstract :
Summary form only given. Circular dots of Permalloy with an appropriate aspect ratio can exhibit a vortex structure with perpendicular magnetization at the core. We investigate the dynamic properties of some dots with the above mentioned characteristics by Brillouin light scattering (BLS) from thermally excited spin waves.
