how can the RSJ (Resistive shunted junction) model be fit to the experimental data of micron-sized (l=10,w=100) SQUID junction made up of SS'S type weak link?
Hi, Rajni! You can try and use PSCAN2: it's a python-based software with which you create a circuital net of JJs, inductors, resistors, etc., so you can design not only your Squid, but also your experimental setup. You can simulate the IV curves calculating the voltage across two nodes in the circuit when applying a certain bias current, specifically setting the RSJ to model the JJs. You need to check whether your output is in line with a S' barrier, though, since as far as I know JJs in this software are standard insulating SIS JJs. However, we recently used PSCAN2 to model the IVs of more complicated and unconventional JJs with a Spin-filter barrier, and it works pretty fine! If you need some references, check our paper - >https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.13.014017
Good luck!
Dear Halima, thank you for your reply and for sharing your work. I will go through it. In our case, the S' is the YBCO superconductor working as a weak link.
Super cool! Indeed, YBCO is more than unconventional, so you'll probably need to check first what are the conditions for which you can actually use this software. But anyway, in its documentation you can take a look at the theory behind it, and choose whether is fine for you or not! :) Cheers!
