Hi Guys!!!!
Today i was taught about the miessner effect in superconductors.The main theme is that when the material in normal state is taken to its transition temparature(Tc)then they will accquire the nature of superconductivity and now if a magnetic field is applied then the substance will mirror the magnetic field and this canm be compared to perfect diamagnetism.So here when the magnetic field is taken above the Ho it will cause the material to loose its superconducting state. But all this theory is virtually applicable only to subatances which are primarily paramagnetic or ferromagnetic in their natural state. So what about the materials which are diamagnetic even in their normal state such as some ceramic compound like (YBCO)?How this theory can explain these materials?
