From: Emergence of Multiple Superconducting Phases in (NH3)yMxFeSe (M: Na and Li)

(a) M / H vs. T plots of (NH3)yLi0.1FeSe in ZFC and FC modes (H = 20 Oe). Inset in (a) shows the method used to determine Tc. (b) Tc vs. x plot in (NH3)yLixFeSe. (c) XRD patterns of (NH3)yLixFeSe at x = 0.1 to 0.9. (d) c vs. x plots in (NH3)yLixFeSe; x is nominal value.
