Figure 2
ρxx(B) at selected temperatures T for the 6-nm-thick film.
From top to bottom at B = 2 T: (a) T = 3 K, 4 K and 6 K; (b) T = 0.328 K, 0.914 K, 1.568 K and 1.980 K. The red curves represent the best fits to Eq. (1) over the limited field range (Bp ≤ B ≤ 2 T) and the blue curves denote the extrapolations of the fits to low B regime using the extracted parameters. The black and blue arrows indicate the experimentally obtained and theoretically predicted peak positions. To emphasize the zero-resistivity superconducting state around B = 0 when T ≤ 1.980 K, the full-scale view at the corresponding T are shown in the inset of (b). (c) ρxx(T) at various B around the superconducting transition.
