In this paper, we study (2+1)-dimensional non-linear spin dynamics of Heisenberg ferromagnetic spin chains equation (HFSCE) for various soliton solutions. We obtain two types of optical solitons i.e. chirp free and chirped solitons. We obtain bright and bright-like soliton, singular-like solitons, periodic and rational solutions, Weierstrass elliptic functions solutions and other solitary wave solutions for HFSCE with the aid of sub-ODE method. At the end, we present graphical representation of our solutions.

海森堡铁磁自旋链模型的啁啾和无啁啾光学孤子

在本文中，我们研究了各种孤子解的海森堡铁磁自旋链方程（HFSCE）的（2+1）维非线性自旋动力学。我们得到两种类型的光孤子，即无啁啾孤子和啁啾孤子。借助sub-ODE方法，我们得到了HFSCE的亮类亮孤子、类奇异孤子、周期有理解、Weierstrass椭圆函数解等孤波解。最后，我们展示了我们的解决方案的图形表示。
