Superconducting phase diagram and FFLO signature in $\lambda$-(BETS)${}_2$GaCl${}_4$ from rf penetration depth measurements

William A. Coniglio, Laurel E. Winter, Kyuil Cho +3

We report the phase diagram of $\lambda$-(BETS)${}_2$GaCl${}_4$ from rf penetration depth measurements with a tunnel diode oscillator in a pulsed magnetic field. We examined four samples wit…
