摘要：
The measurements of ferromagnetic resonance spectra of tangentially magnetized arrays of micron size rectangular particles of permalloy produced by electron-beam lithography are reported. In contrast to continuous films, the spectra of arrays include a number of additional resonance peaks associated with spin-wave modes in the particles. The number of the peaks and their position depends on the angle between the direction of the bias magnetic field and the array axis. The magnetic structure of the particles was investigated using magnetic force microscopy. Magnetization reversal processes of the array were investigated using magneto-optic Kerr effect.
