Abstract
We present a tool for calculations of Fourier transform spatial distribution taken from magnetization dynamics simulated in Object Oriented Micromagnetic Framework (OOMMF). In OOMMF, as well as in other popular micromagnetic software, output data is organized as magnetization vectors from each simulation cell written down to separate file for each simulation step. Therefore, we use parallel computations to reorganize data in files containing time evolution for each cell. Fast Fourier transform is obtained for selected time period by parallel computations using Matlab. The output is a spatial distribution of the magnitude for the selected frequency in the sample cross-section. It allows for analysis of spin waves localization and therefore helps to understand their origin in investigated sample.
