边界条件对磁摩擦的影响
Effects of Boundary Conditions on Magnetic Friction
摘要:
本文研究了有限厚度铁磁伊辛模型的两个正方晶格之间的磁摩擦。我们分析了边界条件和样品厚度的依赖性。Monte Carlo模拟结果表明,该装置使我们能够控制摩擦力的磁场的边界。此外,我们证实了摩擦力的温度导数以及边界能的温度导数在速度依赖的临界温度处具有奇异性。
英文摘要:
We consider magnetic friction between two square lattices of the ferromagnetic Ising model of finite thickness. We analyze the dependence on the boundary conditions and the sample thickness. Monte Carlo results indicate that the setup enables us to control the frictional force by magnetic fields on the boundaries. In addition, we confirm that the temperature derivative of the frictional force as well as that of the boundary energy has singularity at a velocity-dependent critical temperature.
