摘要: Extensive Langevin dynamics simulations are used to characterize the adsorption transition of a flexible magnetic filament grafted onto an attractive planar surface. Our results identify different structural transitions at ratios thermal energy surface attraction strength: straightening, adsorption, and flux closure. The temperature is found be higher in comparison equivalent nonmagnetic chain. has been also investigated under application static homogeneous external field. We that strength orientation field can control process, providing precise switching mechanism. Interestingly, we have observed characteristic tilt angle point related by simple power law.
