Abstract
Ferromagnetic resonance response for X band in the arrays of the cylindrical submicron dots of the permalloy Ni80Fe20 was investigated. Resonance Magnetic field — resonance frequency dependences for arrays of nanodots with D = 4000 nm and D = 500 nm have a D = 300 nm been obtained. Approximation of the experimental data has been performed. The satisfactory coincidence of experimental data with the approximating curves has been achieved in suggestion of the additional field presence. It has been founded that the magnitude of this field in the investigated samples increases with the dot diameter decreasing. Besides that, the presence of the in-plane anisotropy in the samples of small diameter is most probably. The experimental results are confirmed by measurement of the angular dependence of resonance fields in plane of the film.
