The and curves for a 2-UC film (S2) at different frequencies [MHz]: 3 (triangles), 26 (squares), and 500 (circles), calculated from raw , , and data. The solid lines are a guide for the eye. The inset shows the experimental setup.
Temperature dependence of for 1- and 2-UC films (S1) at and different magnetic fields [mT]: 0 (circles), 2 (squares), 3 (triangles), and 4 (crosses). The solid lines curves shows at zero field. The thin solid lines are quadratic fits to below and for magnetic field data. Also shown is the theoretical BKT function (dashed line).
Temperature dependence of dc (squares), (circles) at and at (solid line) for a 3-UC sample (S1). Inset shows the universal plot: vs . Arrows indicate the values determined from the dc resistivity, loss function at and MW measurements .
The penetration depth derived from vs normalized temperature for: 1-UC (crosses), 2-UC (squares) and 3-UC (circles) films.
Temperature variations of for sample. The inset shows versus BCS reduced temperature.
Superfluid density, , of the single crystal sample and thin film (crosses). The predicted behavior of within the two-band model as described in the text is shown by the solid, dashed ( band) and dotted ( band) lines. The solid line represent BCS fit of data using as fit parameter.
Magnetic field variation of of a single crystal sample at different temperatures [K]: 5.66, 5.53, 5.02, 4.06, 3.45, 2.84, 2.15 and 1.43, from left to right. The solid lines are a guide for the eye. The arrow describes how has been deduced.
Temperature variations of of . Symbols: the onset data determined from (circles) and (squares). Dotted line is the BCS data determined from the HW formula.33
