What is the lower limit for experimentally measuring $T_c$ of superconductors?
I'm pretty new to this topic, but find it interesting, so please bear with me.
Since superconductors with $T_c \approx 4.2\text{K}$ have been measured, I wonder, is it possible to have superconductors ...

Is superconductance restricted to an extremely low temperature? Or can it be effectively replicated using some other technique? [closed]
A type of electrical amplifier is proposed in which only magnetism and it’s analogous current exists for the most part. There is no voltage and no wattage (to speak of) in which electricity has to ...

Is there any positive temperature from which superconductivity ceases?
From what I understand about superconductivity, it is due to a coupling between Cooper pairs and phonons. At the absolute 0, there is no phonon, so I assume superconductivity cannot exist at that ...

Are room temperature superconductors theoretically possible, and through what mechanism?
At the moment, the highest critical temperature superconductor known to science (or myself, at least) is mercury barium calcium copper oxide. With a $T_{c}$ of roughly 133 K, that's well above the ...
