I have some very basic questions about the figure on display. It is the first time I look at this matter.
Is this the DC current-voltage curve of a sample of the material in question, without other shenanigans?
Is the “M” phase ohmic, i.e. current is proportional to voltage? It seems so to me by squinting at the graph, because it’s 2-3 mV and 150-250 mA, but I’m not confident because it’s in log scale without a grid.
Is the “N” phase ohmic too?
Are then the I, J, K, L phases superconducting?
Is also M superconducting? If it’s a very short piece of metal, it seems realistic to me to get a resistance of 2 mV/150 mA = 13 mΩ (left M tip) without superconducting properties. So my impression is M = conductor, N = poor conductor, but I’m in doubt it could be M superconductor, N conductor.
