“…In the referred paper Kittel's equations for ferromagnetic resonance (FMR) were used and tted with the data obtained by micromagnetic simulation. Saavedra et al [9] presented studies on the behavior of pentagonal spin ice lattices structures dominated by dipolar effects. In another study, the authors showed the effects of shape on magnetic susceptibility in a stadium-like planar structure [10].…”

Ferromagnetic resonance (FMR) by micromagnetic simulation was carried out in Py circular-shaped films with 2 µm area and thickness of 50 nm. Another geometry with stadium-like format (1 µm of minor axes and 4 µm of major axis) was studied. Ferromagnetic resonance by simulation with an in plane and perpendicular external magnetic field show differences in results if compared the two geometries. The results are relevant, as the dimensions of these objects present an aspect ratio of more than 20 times (side dimension/thickness). The results are quite different as the magnetization maps are different for the two geometries. Even working in the field enough to saturate the material. Analyzes were performed using Kittel's equations for FMR.
