Figure 6: Susceptibility of normal state for phenanthrene and A3phenanthrene.
From: Superconductivity at 5 K in alkali-metal-doped phenanthrene
The magnetic susceptibility as a function of temperature was measured under 5 T. The fitting curves comes from the formula χ=χ0+C/(T+θ), where χ0 is a constant, C is Curie constant, and θ is the paramagnetic Curie temperature. χ0 is negative for pure phenanthrene while positive in the superconducting K3phenanthrene and Rb3phenanthrene. The fitting results between 4 and 80 K are listed in Table 3.
