In the present study, the magnetic configurations of magnetic nanostructure consisting of alternate magnetic and non-magnetic layers arranged within a multilayer nanowire structure are investigated. We report the angular dependent hysteresis properties of Ising-type multilayer nanowire (IMN) on hexagonal structure by the effective-field theory with correlations. The phase diagrams are presented in the different planes as function of coercivity (H (C)) and remanence (M (r)) to investigate the soft/hard magnetic behaviors of the system. The system exhibits different hysteresis properties and soft/hard magnetic behaviors as a result of angular, thermal, and geometrical variations. In the cases of the increasing temperature, angle (phi), as well as the wire length (r) and shell length (s), a decrease in the magnetic hardness are observed. Moreover, if the p increases, the system illustrates more soft magnetic properties. Comparisons between the observed theoretical results and some experimental works of nanowire with hysteresis behaviors are made and a very good agreement is obtained.
