Abstract :
Improved formulas are obtained to provide more accurate determination of magnetic bubble material parameters such as material length 
and saturation magnetization 
based on the measurements of domain stripe width and bubble collapse field. The improvement takes into consideration the effects of finite uniaxial anisotropy parameter 
in the formulas. These improved formulas are based on the numerical results obtained from micromagnetic domain calculations of periodic stripes and of an isolated axisymmetric bubble.
and saturation magnetization based on the measurements of domain stripe width and bubble collapse field. The improvement takes into consideration the effects of finite uniaxial anisotropy parameter in the formulas. These improved formulas are based on the numerical results obtained from micromagnetic domain calculations of periodic stripes and of an isolated axisymmetric bubble.Keywords :
