Superconductor-to-Metal Quantum Phase Transition in Overdoped $L a_{2 - x} S r_{x} C u O_{4}$

T. R. Lemberger, I. Hetel, A. Tsukada +2

We investigate $T_{c}$ and magnetic penetration depth $λ (T)$ near the superconductor-metal quantum phase transition in overdoped $L a_{2 - x} S r_{x} C u O_{4}$ films. Both $T_{c}$ and superfl…

Anomalously Sharp Superconducting Transitions in Overdoped $L a_{2 - x} S r_{x} C u O_{4}$ Films

T. R. Lemberger, I. Hetel, A. Tsukada +1

We present measurements of $ab$ -plane resistivity $ρ_{ab} (T)$ and superfluid density [ $\propto λ^{- 2}$ , $λ$ = magnetic penetration depth] in $L a_{2 - x} S r_{x} C u O_{4}$ films. As Sr co…

Superfluid density of superconductor-ferromagnet bilayers

Thomas R. Lemberger, Iulian Hetel, Adam J. Hauser +1

We report the first measurements of the effective superfluid density n_S(T) \propto λ^{-2}(T) of Superconductor-Ferromagnet (SC/FM) bilayers, where λis the effective magnetic field…

Quantum critical behaviour in the superfluid density of strongly underdoped ultrathin cuprate films

Iulian Hetel, Thomas R. Lemberger, Mohit Randeria

A central issue in the physics of high temperature superconductors is to understand superconductivity within a single copper-oxide layer or bilayer, the fundamental structural unit…

Search for Cooper-pair Fluctuations in Severely Underdoped YBCO Films

Y. L. Zuev, I. Hetel, T. R. Lemberger

The preformed-pairs theory of pseudogap physics in high- $T_{C}$ superconductors predicts a nonanalytic $T$ -dependence for the $ab$ -plane superfluid fraction, $ρ_{S}$ , at low temperatur…

Field-dependent diamagnetic transition in magnetic superconductor $S m_{1.85} C e_{0.15} C u O_{4 - y}$

R. Prozorov, D. D. Lawrie, I. Hetel +2

The magnetic penetration depth of single crystal $S m_{1.85} C e_{0.15} Cu O_{4 - y}$ was measured down to 0.4 K in dc fields up to 7 kOe. For insulating $S m_{2} Cu O_{4}$ , Sm $^{3 +}$ …
