摘要：

Discrete spin-wave spectrum of tangentially magnetized cylindrical magnetic dots is calculated taking into account both intradot dipolar and exchange interactions. The case when the dot radius is much larger than the dot height is considered. The quantization effect of the spin-wave frequencies appears due to the finite dot radius. The spectrum of the discrete spin-wave modes is calculated in a practically important case of square array of permalloy (FeNi) cylindrical dots. (C) 2000 Published by Elsevier Science B.V.
