Hi All
I have problem with the resistivity measurements on YBCO thin films.
when I deposited Silver pads (with annealing at 460C) on a non-patterning fresh film I can see zero ohm at Tc (Superconductivity).
But, when I deposited Silver pads(with annealing at 460C) on patterned ybco stip line, I could not see zero ohm (no superconductivity!). I attached the figure of the resistivity measurements in both case.
Width of the lines are 8 to 10um.
Alos I found that the resistance of the strip lines (measured with voltmeter at room temparature) was increasing after the annealing step.
Could be that the oxygen loss from the strips?

Please if any one can help.
