The magnetic and configurational properties of tail-like polymer chain with ferromagnetic ising interaction

Abstract

The magnetic and configurational properties of tail-like polymer chain with nearest-neighbor ferromagnetic lsing 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 Tc. Correspondingly, the collapse phase transition from a random coil structure to a tight sphere is also taken place at Tc. 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 meansquare end-to-end distance (R2) and mean-square radius of gyration (S2). We also found that the number of monomers that are in contact with the surface increases with the decrease of temperature. © 2007 The Society of Polymer Science.
