  • Abstract
    An empirical relation is given for the saturation velocity of a domain wall in a bubble domain garnet material. The relation is v_{o3} = 0.4\\pi\\gamma M(A/K_{u})^{1/2} , where V_{o3} is the saturation velocity, γ the gyromagnetic ratio, 4\\pi M the saturation magnetization, A the exchange constant and Kuthe uniaxial anisotropy constant. The relation provides a close approximation for a wide range of experimental data. Comparisons between experimental data and theoretical data are made. A possible interpretation of the empirical relation is given.
