The Hall coefficient (R_H) is investigated along the in-plane direction for carefully prepared La_2-x_Sr_x_CuO_4_ thin films from x=0.08 to x=0.40. It is found that R_H becomes almost temperature independent around room temperature for x >=…

Transport properties of Nd$_{2-x}$Ce$_x$CuO$_{4+\delta}$ single crystal films are investigated in magnetic fields $B$ up to 9T at $T$=(0.4-4.2)K. An analysis of normal state (at $B>B_{c2}$) Hall coefficient $R_H$$^n$ dependence on Ce doping…

The critical temperature of an underdoped cuprate superconductor is limited by its phase stiffness $\rho$. In this Letter we argue that the dependence of $\rho$ on doping $x$ should be understood as a consequence of deleterious competition…
