confirmed that MgB_2 have a transition temperature around
40k. If this is true, it is really a joke designed by God.
Before the current high Tc cuprate superconductor was
discovered in 1986, people have tried a lot of material to
increase Tc. However, the highest Tc they achieved is only
23k. Therefore, when two european physicist reported that
LaSrCuO has Tc over 30k in 1986, people believed a big
progress was made. For a person like me, |
