Analytical and numerical methods are used to investigate the new localized states of a surface magnetostatic wave envelope in a ferromagnet–dielectric–metal structure in the framework of the extended non-linear Schrödinger equation. The problems of the modulation instability of homogeneous states and long-wavelength modulation of a monochromatic wave in the vicinity of a ‘zero-dispersion’ point are discussed. The excitation conditions for a multi-soliton state are analysed. It is shown that a certain threshold amplitude of the initial distribution should be reached for the excitation of these states, while no such threshold exists for the one-soliton state. The possibility of the experimental observation of the above-mentioned non-linear states is discussed.
