In the present study, a theoretical approach to investigate the magnetic hysteresis properties in barcode nanowire are used and applied to study Ising system on hexagonal structure. The hysteresis behaviors of Ising-type barcode nanowire (IBN) are studied within the effective-field theory with correlations. The effects of the composition (p), temperature (T) and geometry (interlayer length (d), shell length (s), and wire length (r)) on the hysteresis behaviors are examined in detail. The phase diagrams are presented in the five different planes, namely (p, T), (d, r), (d,T), (r, T) and (s, T) as function of coercive field (HC) and remanence (Mr), and investigated soft/hard the magnetic characteristics of the system. We find that the hysteresis loops areas decrease case as the temperature, wire and lengths increase. Moreover, when p increases the hysteresis loop areas increase. Moreover, HC exhibits an increase in around d = 1 value, then HC does not change with the increasing d values. Theoretical results have qualitatively compatible with some experimental works of multilayer nanowire.
