A Is the Earth's core a potential high-temperature superconductor?

Hello to all

Can we consider the core of the Earth to be a superconductor ,for example Aragon national laboratory hinted for some thing like that

That been said , what test could verify or disprove this idea

No, not really.
There are perhaps compounds in the core that would superconduct if you cooled them to a low enough temperature; but the temperature a the core is high not low.

Note that there are LOTS of materials that can superconduct; (nearly) all the metals in the periodic system can be made to superconduct at low enough temperatures and/or high enough pressure. There are also lots of superconducting compounds.
Some, like MgB2 , had been in use for many, many years before someone realized that they became superconducting at relatively high temperatures

First of all, it is "Argonne", not "Aragon. I used to work there, so I'm "sensitive" about someone mangling the name.

Secondly, it is well-known that one can get elevated transition temperatures at high pressures for several superconductors. So this isn't new. However, to say that the hot, heated core of our Earth is a superconductor simply due to the high pressure is a stretch by any imagination. As has been stated, the core is at such a high temperature, it would melt if it were not under pressure.

Sorry for the mistake in the name

Pressurised superconductors are achieved for LaH10

Dose NiFe able to become a superconductors under high pressure.

And another question the core is solid metal ?
