Experimental evidence for Fröhlich superconductivity in high magnetic fields

Resistivity and irreversible magnetization data taken within the high magnetic field CDW x phase of the quasi-two-dimensional organic metal α-(BEDT-TTF) 2 KHg(SCN) 4 are shown to be consistent with a field-induced inhomogeneous superconducting phase. In-plane skin depth measurements show that the resistive transition on entering the CDW x phase is both isotropic and representative of the bulk.
