Monte Carlo simulation of magnetic nanostructured thin films

Using Monte Carlo simulation, we have compared the magnetic properties between nanostructured thin films and two-dimensional crystalline solids. The dependence of nanostructured properties on the interaction between particles that constitute the nanostructured thin films is also studied. The result shows that the parameters in the interaction potential have an important effect on the properties of nanostructured thin films at the transition temperatures.     

钠离子浓度对核小体纤维结构影响的Monte Carlo模拟

通过核小体纤维模型的构建，利用Monto Carlo方法模拟其在各种钠离子浓度的溶液中结构变化的过程.模拟结果显示当溶液的钠离子浓度增大时，核小体由锯齿状结构转变为螺旋状结构.在常温所得到的核小体结构参数与实验结果接近，较好地解释了溶液中的钠离子浓度对核小体纤维结构的影响. 关键词： 核小体纤维 超螺旋结构 Monte Carlo方法 钠离子浓度
