It is shown that s-wave superconductors in the presence of antiferromagnetic (AF), or spiral (S) magnetic structure have such anomalous properties at low temperatures that heavy ferminon superconductivity (HFS) can be interpreted in this picture. We calculate: a specific heat C(e) = A1T2, thermal conductivity kappa-xx = A2T2, sound absorption GAMMA = A3T + BT3, NMR rate T1(-1) = A4T3, quasiparticle conductivity sigma-s(q.p) = A5T, thermoelectric power Q(xx) = A6T and penetration depth lambda-xx2 = lambda-0(2) + A7T, where A(i) depend on magnetic structure, and are anisotropic even in the isotropic system. Various mechanisms contributing to GAMMA are studied for ql << 1 and ql >> 1. The setup based on HFS are proposed in order to prove the existence of thermoelectric effects in superconductors. The theory is applied to the HFS UPt3, but it is also suitable for other HFS UBe13, CeCu2Si2, URu2Si2, as well as for some magnetic superconductors like ErRh4B4, HoMo6S8.
