We report results from a systematic study of the competition of exotic triplet pair density wave (PDW) superconductivity (SC) with homogeneous (zero pair momentum) SC in strongly polarized media such as half metallic systems. From the two different PDW states allowed by symmetry in this background only one may dominate or even coexist with homogeneous SC. We propose a direct experimental identification of PDW SC in this context. Our results suggest that these exotic states may plausibly emerge in heterostructures involving proximity of SC with half-metallic CrO2 where induced SC is established in the half metallic region and in strongly ferromagnetic superconductors.
