Abstract

We study magnetic behaviors of phase diagrams and hysteresis loops in a cubic, hexagonal, and cylindrical type transverse Ising nanowire within the effective-field theory with correlations. From these studies, we investigate the influence of the shape on magnetic properties of Ising nanostructures. We find that the behavior of phase diagrams is more similar for the cubic and hexagonal nanowires than the cylindrical one and the system undergoes a second-order phase transition at the lowest temperature for the hexagonal nanowire and at the highest temperature for the cylindrical one. Hysteresis loop areas are the largest for a hexagonal nanowire and smallest for a cylindrical one. Hysteresis loop areas disappear at the highest temperature for a cylindrical nanowire and at the lowest temperature for a cubic one.
