Ultrathin underdoped films of YBa 2 Cu 3 O 7− δ (YBCO) exhibit a prominent and abrupt downturn in ab -plane superfluid density n S ( T ) at a temperature consistent with a 2D vortex-pair unbinding transition. In this paper, we show that this chara

We have measured the vortex pinning strength in thin films of the electron-doped cuprate La 2-x Ce x CuO 4 for various doping x from x = 0.075 (T c = 25 K) to x = 0.15 (T c = 12.5 K). The optimal doping for this compound is x ≃ 0.11, at which T c =

From measurements of the magnetic penetration depth, λ(T), from 1.6 K to T c in films of electron-doped cuprates La 2-x Ge x CuO 4-y and Pr 2-x Ge x CuO 4-y we obtain the normalized density of states, N s (E) at T = 0 by using a simple model. In thi

A correlation between the superfluid density n s(T) ∝ 1/λ2 ab(T) at low temperatures and the nanoscopic disorder in the a–b planes of YBCO thin films has been revealed. It has been found that a degree of this disorder can be determined from the

We report measurements of the inverse squared magnetic penetration depth, lambda(-2)(T), in Pr(2-x)Ce(x)CuO(4-delta) (0.115< or =x < or =0.152) superconducting films grown on SrTiO3 (001) substrates coated with a buffer layer of insulating Pr2CuO4. l

We present measurements of the magnetic penetration depth, λ - 2 (T). in Pr 2 - x Ce x CuO 4 - y and La 2 - x Ce x CuO 4 - y films at three Ce doping levels, x, near optimal. Optimal and overdoped films are qualitatively and quantitatively different

We present measurements of the ab-plane magnetic penetration depth, lambda(T), in five optimally doped Pr(1.855)Ce(0.145)CuO(4-y) films for 1.6 K< or =T < or =T(c) approximately 24 K. Low resistivities, high superfluid densities n(s)(T) proportional,

The magnetic penetration depth, $\lambda^{-2}(T)$, in the basal plane of a magnesium diboride (MgB$_2$) film was measured using a two-coil mutual inductance technique at 50 kHz. This film has $T_c\simeq 38$ K, $\Delta T_c \leq 1$ K, and $\lambda(0)\s
