  A quantal model description of a discrete localized skyrmion singularity
embedded in a ferromagnetic environment is proposed. It allows discussing the
importance of various parameters in the appearance of a quantal skyrmion
singularity. Analysis of the skyrmion reveals a few specific quantal
properties: presence of a whole series of skyrmion states, non-classical nature
of the local spins, presence of superposition states and presence of
extra-skyrmion states due to the quantization of the central spin of the
singularity. The interaction of an electron, tunneling or substrate, with the
skyrmion is also described allowing a new view at the origin of the skyrmion
stability as well as the possibility to discriminate between ferromagnetic and
skyrmion phase in an Inelastic Electron Tunneling Spectroscopy (IETS)
experiment, based on the skyrmion quantal properties.
