Query: Adsorption transition of a grafted ferromagnetic filament controlled by
  external magnetic fields   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 different ratios of the thermal energy to the surface attraction
strength: filament straightening, adsorption and the magnetic flux closure. The
adsorption temperature of a magnetic filament is found to be higher in
comparison to an equivalent nonmagnetic chain. The adsorption has been also
investigated under the application of a static homogeneous external magnetic
field. We found that the strength and the orientation of the field can be used
to control the adsorption process, providing a precise switching mechanism.
Interestingly, we have observed that the characteristic field strength and tilt
angle at the adsorption point are related by a simple power law.
