Изменение направления оси легкого намагничивания массивов сегментированных нанонитей Ni/Cu с увеличением длины сегмента Ni

Abstract

Arrays of ordered segmented nanowires are considered as a promising material for three-dimensional information storage systems. However, the presence of a large number of competing interactions significantly complicates the description of the magnetic behavior of such systems. In this work, the influence of the length of the nickel segment on the integral magnetic properties of the array is investigated. In particular, it is shown that the change in the direction of the easy axis of magnetization occurs when the segment length to diameter ratio is in the range from 10 to 20.
