The Magnetic and Configurational Properties of Tail-Like Polymer Chain with Ferromagnetic Ising Interaction

The magnetic and configurational properties of tail-like polymer chain with nearest-neighbor ferromagnetic Ising interaction were studied by Monte Carlo method. The results show that the tail-like polymer chain has spontaneous magnetization at temperatures below the critical temperature T c . Correspondingly, the collapse phase transition from a random coil structure to a tight sphere is also taken place at T c . We found the surface does not play visible effect on the magnetization and energy at any temperature. However it affects the size of chains, such as the mean-square end-to-end distance < R 2 > and mean-square radius of gyration < S 2 >. We also found that the number of monomers that are in contact with the surface increases with the decrease of temperature.
