在扩散限制凝聚模型基础上引入粒子的自旋自由度(包括自旋向上和向下),将自旋耦合系数扩展为随粒子间距离幂次变化的非常数项J/rα,采用Monte Carlo方法研究了在二维三角点阵基底上不同幂指数α以及耦合强度系数J值磁性粒子的分形生长规律,给出了此类磁性分形团簇的自旋分布、磁化强度等随模型参数的演化规律。
Based on the diffusion-limited agglomeration model, the spin degrees of freedom of the particles (including the spin up and down) are introduced, and the spin coupling coefficient is expanded to a non-constant J / rα varying with the distance between the particles. The Monte Carlo method The fractal growth law of magnetic particles with different power exponents α and coupling strength coefficients J on two-dimensional triangular lattice substrates was studied. The spin distribution and magnetization of such magnetic fractal clusters with the evolution of model parameters .
