An optimization method is proposed for calculating the radius of magnetic skyrmions or skyrmion-like structures based on the simulation data from discrete micromagnetic model,by employingthe cubic spline interpolation algorithm combined with Fourier series expansion method.Using this method,the circular and elliptical shaped skyrmions have been analized.The results show that the influence of the discrete model on data sampling can be effectively reduced and the calculation accuracy of the radius of skyrmion or skyrmion-like structures is improved.The proposed method may be instructive to quantitatively characterize the shape changes of these magnetic structures in the dynamic processes,and to study the new emerging physical phenomena and mechanisms caused by their deformation.
