We analyzed two cases of current-phase relation with additional terms to the first harmonic sin ?: a case of the second harmonic sin 2? and the case of the fractional term sin (?/2). It is shown that the changing of the return current of dc SQUID on junctions with unconventional current-phase rela-tion is determined by the amplitude of the second term in current-phase relation, geometrical inductance, and ex-ternal magnetic field. © I.
