Which properties are sufficient evidence for a material to be not superconducting? I am looking for a set of statements like
If the material is semiconducting, it is not superconducting
Edit: I am not looking for a definition of superconductivity, or for introductional literature like the famous W. Buckel.
I am looking for properties, that would forbid superconductivity. If you have a source for it i would be very glad. As far I remember magnetic atoms will forbid superconductivity too, but i could not find a source yet.
