MIT study finds natural graphite can host multiple superconducting states that strengthen under magnetic fields
By
Jennifer Chu | MIT News
Summary
MIT researchers have discovered that a microscopic structure found in natural graphite (the material in pencil lead) can host multiple superconducting states — a rare phenomenon where a single material exhibits different forms of zero-resistance electron flow. Surprisingly, these superconducting states actually strengthen when exposed to a magnetic field, contrary to typical superconductor behavior. The findings, published in Nature, reveal that ordinary graphite is far more complex at the microscale than previously understood.

· 3 pulledWhile there are thousands of materials that are known to be superconductors, it is rare for one material to host multiple forms of superconductivity.
The ordinary graphite in pencil lead is proving to be surprisingly multifaceted at the microscale.
In a further surprise, these superconducting states even get stronger when exposed to a magnetic field.
