The competition between spin glass (SG) and antiferromagnetic order (AF) is analyzed in two-sublattice fermionic Ising models in the presence of a transverse G and a parallel H magnetic fields. The exchange interaction follows a Gaussian probability distribution with mean Γ€4J 0 =N and standard devia
