This paper is a highly cited seminal paper detailing the maths involved when considering wide junctions (larger than the Josephson penetration depth)
The details of the calculations are not too important here – instead, the resulting behaviour of the critical current in field (c.f. Fig 4 and Fig 5) is the focus

This paper deals with an important issue for experimentalists dealing with HTS materials that inevitably require soldering i.e. the application of heat for various time periods. It also addresses the conflicting behaviours of HTS and copper that are joined together at elevated temperatures.
See Jack Ekin, Chapter 8 that, in part, deals with some associated HTS contact issues

This is a long paper that I haven’t read myself for over a decade. However, it provides a very good overview of mechanical ball milling, which is a process that was a prominent experimental tool in the Group when I joined and one I used myself to fabricate nanocrystalline niobium carbonitride. The milling equipment we have in the Group is discussed in sections 4.2.1 (Spex shaker mill) and 4.2.2. (planetary ball mill). There’s no need to read the whole paper in detail, but looking through the contents list will give some idea of the scope of the process and then a slightly more detailed look through section 4.3 and 12 should suffice.

Charlie| D. Dew-Hughes, “Flux pinning mechanisms in type II superconductors,” Philosophical Magazine, vol. 30, no. 2, pp. 293-305, 1974
Dew-Hughes determines the field-dependence of the volume-averaged pinning force by simple consideration of the interaction strength and range, and the total pinned fluxon length.
Chapters 6 and 7 of Matsushita discuss material which is relevant to this paper. They are quite advanced by comparison but they do contain some helpful diagrams

This paper gives some nice context for understanding 2D simulations. I think it gives a very nice overview of the methods and outputs for the TDGL 2D code. In particular, it illustrates how a transport current is simply simulated by fixing the fields at the edges – with the useful interpretation that the superconductor does not distinguish between different ’types’ of fields.
