The experimental studies of these ecitations allows the determination of basic magnetic parameters, like exchange constants, magnetic anisotropy, g-factors, etc. The application of the magnetic field significantly enhances such characterization by analyzing the two-dimensional map of resonance frequencies vs magnetic field.
