摘要

Microwave properties of an array of magnetic nanodots in a ferromagnetic state having a point defect - a dot with inverted magnetization or different material parameters - are considered. The existence of a single point defect in a dot array may lead to the appearance of several localized modes: one 'defect' eigenmode and several 'well' modes, the number and structure of which strongly depend on the magnetostatic interaction between the dots. It is shown that by performing a ferromagnetic resonance /201FMR/202 experiment in an array of magnetic dots containing a small number of defects it is possible to obtain the information about the entire spin-wave spectrum of the array.
