Effects of Finite Anisotropy Parameter Q in the Determination of Magnetic Bubble Material Parameters
Abstract
Improved formulas are obtained to provide more accurate determination of magnetic bubble material parameters such as material length (l) and saturation magnetization (Ms) based on the measurements of domain stripe width and bubble collapse field. The improvement takes into consideration the effects of finite uniaxial anisotropy parameter (Q) 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.
