Figure 3: Temperature dependence of magnetization (χ) for A3phenanthrene.
From: Superconductivity at 5 K in alkali-metal-doped phenanthrene
(a) χ versus T plots for powder samples of K3phenanthrene with Tc=4.95 K and Rb3phenanthrene with Tc=4.75 K in the ZFC and FC measurements under 10 Oe, and the shield fractions are 5.3% and 6.7%, respectively. The right inset exhibits the χ versus T plot of the K3phenanthrene pellet sample by pressing powder, and a shielding fraction of 15.5% was achieved. M versus H plot for K3phenanthrene at 2.5 K was shown in the left inset. (b) χ versus T plots for the K3phenanthrene powder sample in ZFC measurements under different H. The H versus Tc plot is shown in the inset. The onset temperature (Tconset) is defined as Tc.
