Abstract: In a Relaxation Oscillation SQUID (ROS), the magnetic fields (Self-Magnetic Fields, i.e. SMF) generated by the current in the shunt circuit coupled to the SQUID loop. It has been proven that SMF caused asymmetry and a shift of the magnetic flux-frequency ($Phi-f) characteristics and the frequency fluctuation. The calculated results of the $Phi-f curve taking account of the SMF are in good agreement with the experiment results. The asymmetric $PHI-f curve provides a larger df/d$Phi, which leads to the good flux resolution. While the frequency fluctuation, which is observed as the broad spectrum, increases in proportion to the transfer coefficient (df/d$Phi). The SMF depends on the mutual inductance between the shunt inductance and the SQUID loop. !7
