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

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
https://www.anl.gov/article/nickel-for-thought-compound-shows-potential-for-hightemperature-superconductivity

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

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 ?
