In this paper, we investigate the superconducting proximity effect for a superconductor with three types of singlet, OSP and ESP triplet pairings in contact with a clean ferromagnetic region. Using the quasiclassical Green’s function approach, we calculate the superconducting pair amplitude function in terms of the characteristic parameters of the system and compare penetration of these superconducting correlations inside the ferromagnetic region. We show that the ESP triplet correlations have a long range thermal penetration compared with the singlet and OSP triplet correlations inside the ferromagnetic region.
