  We study theoretically the asymptotic behavior of the Shiba bound states
associated with magnetic impurities embedded in both 2D and 1D anomalous
superconductors. We calculate analytically the spatial dependence of the local
density of states together with the spin polarization associated with the Shiba
bound states. We show that the latter quantity exhibits drastic differences
between s-wave and different types of p-wave superconductors. Such properties,
which could be measured using spin-polarized STM, offer therefore a way to
discriminate between singlet and triplet pairing in low-dimensional
superconductors, as well as a way to estimate the amplitude of the triplet
pairing in these systems.
