dc.descriptionSupplementary information for our manuscript, entitled 'Spontaneous Skyrmion Ground States of Magnetic Metals', cond-mat/0603103, is presented. The physical nature of the gradient terms of our generalized micromagnetic model for ferromagnets with softened longitudinal fluctuations is explained. The relationship of our micromagnetic model with the spin fluctuation theory of itinerant-electron magnets is discussed. Experimental estimates of the parameter eta, which accounts for an effective reduced longitudinal stiffness, are presented for real materials from published polarized neutron scattering experiments on EuS, Ni and MnSi. The available experimental data clearly show that eta is significantly reduced for the latter two systems. It is suggested that particle-hole excitations are at the root of this longitudinal softness in itinerant-electron ferromagnets. The current status of the experimental evidence supporting spontaneous, amorphous skyrmion textures in MnSi and other materials is reviewed. Finally, we also address the general potential of skyrmion textures in chiral magnets for other fields of physics.
