Abstract

The effect of dipolar interactions among cylindrical nanodots, with a vortex–core magnetic configuration, is analyzed by means of analytical calculations. The cylinders are placed in a N × N square array in two configurations—cores oriented parallel to each other and with antiparallel alignment between nearest neighbors. Results comprise the variation in the core radius with the number of interacting dots, the distance between them and dot height. The dipolar interdot coupling leads to a decrease (increase) of the core radius for parallel (antiparallel) arrays.
