  The thermodynamic and magnetic properties of the mixed spin (1/2-1) hexagonal
Ising nanowire (HIN) system with core-shell structure have been presented by
means of the effective-field theory (EFT) with correlations. The effects of the
physical parameters of the system on thermodynmaic and magnetic properties
(magnetizations, susceptibilities, internal energies, and free energies and
hysteresis curves) are investigated for both ferromagnetic and
antiferromagnetic case, in detail. One can find that when the temperature
increases the hysteresis loop areas decrease and the hysteresis loops disappear
at above critical temperature. Moreover, different hysteresis loop behaviors
have been observed such as single, double and triple hysteresis loops in the
system. In order to confirm the accuracy of the phase transition points, we
also investigate the free energy of the system.
