We propose that screened pairing interactions mediated by phonons could
give rise to a spin triplet superconductivity
in ferromagnetic compounds such as .
It is pointed out that the pairing interactions
include anisotropic components such as those of p-, d-, f-waves
in addition to dominant s-wave component
due to the momentum dependence.
Since the ferromagnetic long-range order coexists,
there is a large splitting of the Fermi surfaces of up and down spin
electrons, which suppresses singlet pairing.
Therefore, triplet pairing occurs at last due to the sub-dominant
anisotropic interactions, even in the absence of magnetic contribution
to the pairing interactions.
