TL;DR: In this paper, the authors used Monte Carlo and iterative methods considering dipolar and higher-order multipole effects to calculate the hysteresis loops of two-dimensional arrays of magnetic nanowires.

TL;DR: In this article, high-quality densely packed hexagonal arrays of Ni nanowires have been prepared by filling self-ordered nanopores in alumina membranes, which have been studied by atomic force, high resolution scanning electron microscopies, Rutherford backscattering, and vibrating sample magnetometer techniques.

TL;DR: In this paper, the magnetic properties of Ni nanowires were investigated by using high-resolution scanning electron microscopy (HRSEM) and magnetic characterization of hexagonally arranged nanowire arrays.

TL;DR: In this article, the influence of geometrical characteristics of arrays of Ni nanowires on their hysteresis loops have been studied, and the authors conclude that magnetic behavior is determined by the balance between different energy contributions, namely, the shape anisotropy of individual nanwires, the magnetostatic interaction among nanwire, and seemingly the magnetoelastic anisotropic interaction induced in the nanowire by the alumina matrix through temperature changes as a consequence of their different thermal expansion coefficients.

TL;DR: In this article, the magnetic properties of arrays of Ni nanowires embedded in porous alumina are reviewed as a function of their spatial ordering, and a model of multipolar interacting nanowire is introduced to account for the influence of short and long range ordering degree of the arrays.
