Abstract
The problem of the frequency spectrum of collective gyrotropic modes in a finite linear chain of magnetostatically interacting ferromagnetic disks has been considered. It has been shown that by analyzing the frequency spectrum, one can derive information about the magnetization eddy state for each of the nanodisks in the chain. The feasibility of recording the frequency spectrum as a tool for data readout in magnetic memory devices has been discussed.
