A Room-Temperature Superconductor? New Developments

Neither lead nor copper are what we would normally consider a "magnetic material" like iron.

That it interacts strongly with a magnetic field shows that a big change in the material, consistent with superconductivity, has occurred.

Quantum level effects are newly appearing in the macroscopic world, and that's always interesting.

Could this not also have a big use case outside of superconductivity? Decellerators or accelerators for maglev trains or similar?

Oh, definintely!

Most materials are diamagnetic, but only very weakly so.

I think that a new room-temperature material that was so strongly diamagnetic that it could lift the weight of its own volume in lead probably would bring some interesting new applications.

For example, anything with a bearing in it used in an application where it's safe to have a strong permanent magnet.
