Hello mate here is your answer.

By changing the inter-atomic spacing, pressure can vary the entire band structure. This can be seen clearly from the fact that there are many examples of pressure-induced solid phase changes (i.e. the bcc-hcp transition of Fe with a bcc-hcp-fcc tripe point at 757K and 10.4GPa). Changes in the phonon spectrum are, of course, reflective of the overall change in inter-atomic potential under pressure. 

Hope it helps you.

Explanation:

Superconductivity is the set of physical properties observed in certain materials, wherein electrical resistance vanishes and from which magnetic flux fields are expelled. Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero. An electric current through a loo
