Charge-density Waves Survive the Pauli Paramagnetic Limit

Abstract

Measurements of the resistance of single crystals of (Per)${}_2$Au(mnt)${}_2$ have been made at magnetic fields $B$ of up to 45 T, exceeding the Pauli paramagnetic limit of $B_{\mathrm{P}}\approx 37$ T. The continued presence of non-linear charge-density wave electrodynamics at $B\ge 37$ T unambiguously establishes the survival of the charge-density wave state above the Pauli paramagnetic limit, and the likely emergence of an inhomogeneous phase analogous to that anticipated to occur in superconductors.
