The magnetic field modulation of the voltage output of a d.c. SQUID, calculated numerically including the phase-dependent dissipation (PDD) term with a negative prefactor epsilon in Josephson junctions, exhibits maxima (minima) at integer (half-integer) values of the magnetic filling factor f in a larger bias current beyond I *, the values of which depends on the inductance parameter beta(L) and the prefactor epsilon. Asymmetry in both junction critical currents and inductances between the two branches of a d.c. SQUID loop does not change the essential feature of the magnetic-field modulation of the resistance due to the PDD effect. Copyright (C) 1996 Elsevier Science Ltd
