By enumerating group-theoretically the antiferromagnetic (AF) states allowedunder the known crystalline symmetry in a representative heavy Fermion supercon-ductor (SC), CeCu.Si., the conditions are examined under which a double transitionof either SC (7'.) or AF (7'.) states occurs. It is predicted that for almost all simpleAF states a splitting of the transition temperature T. or T. can be induced by a nontrivial coupling of the two order parameters, provided that the existing SC statebelongs to a degenerate E. representation.[CeCuz Siz, heavy Fermion superconductor, unconventional pairing state, antifer- ll romagnetism, double transitionl
