Superconductivity in 1T-TaS₂ Defies Magnetic Field Limits

Researchers at the Chinese Academy of Sciences inserted organic molecules between the layers of a 1T-TaS₂ crystal and, under extreme pressure, produced a superconducting state that withstands magnetic fields twice as strong as classical theory predicts. The findings were published in Reports on Progress in Physics.

• Organic intercalation widened the 1T-TaS₂ layers and altered interlayer coupling
• Superconductivity emerged at higher pressure after another ordered state was suppressed
• The material tolerated magnetic fields twice the classical limit
• The technique enables exotic quantum phases in bulk crystals rather than fragile monolayers
