Temperature dependences of the 4-point resistance measured over the dc-SQUID and the junction's loop. We note that just before the superconducting transition that there is a small bump in resistance of the dc-SQUID and a long `tail' before reaching \qty{0}{\ohm}. The transition of the junction's loop is much sharper in comparison.

The sample sadly enough exploded and we were unable to produce any (significant) results. Its remains are shown in Figure~\ref{fig:CP3.5A-remains}. The location of the damage is unexpected. It would be more logical if the junctions had exploded as those are the most fragile due to higher current densities.

There is one noteworthy result for this sample. During our measurements it appeared as though the sample has two critical temperatures. The RT-curves are shown in Figure~\ref{fig:CP3.5A_RT_curves}. The bulk transition of the dc-SQUID appears to be around \qty{7.5}{\kelvin}. The junction's loop transitions around \qty{6}{\kelvin}. In hindsight we think the cause is a significant delay between the sample's thermometer and the sample itself. The delay has not been noted before as we took resistance measurements every few seconds instead of waiting for temperature stability. This could easily be checked if it the sample was still alive.
