Figure 2. Superconductivity in intercalated BP.

Figure 2

(a) Temperature dependence of magnetic susceptibility χ for Li, K, Rb, Cs and Ca intercalation. Shown are ZFC (solid symbols) and FC (open symbols) measurements for an in-plane magnetic field of 10 Oe. The arrow indicates Tc as determined from dχ/dT. The inset shows how Tc was determined for individual samples: It is defined as the sharp change in dχ/dT (see also Supplementary Fig. 4). (b) Magnetization M as a function of magnetic field for our intercalated compounds.
