Abstract
From systematic analysis of the high pulsed magnetic field resistance data of La$_{2-x}$Sr$_x$CuO$_{4}$ thin films, we extract an experimental phase diagram for several doping values ranging from the very underdoped to the very overdoped regimes. Our analysis highlights a competition between charge density waves and superconductivity which is ubiquitous between $x=0.08$ and $x=0.19$ and produces the previously observed double step transition. When suppressed by a strong magnetic field, superconductivity is resilient for two specific doping ranges centered around respectively $x\approx 0.09$ and $x\approx 0.19$ and the characteristic temperature for the onset of the competing charge density wave phase is found to vanish above $x = 0.19$. At $x=1/8$ the two phases are found to coexist exactly at zero magnetic field.
Author comments upon resubmission
We thank the referee for their careful reading of the manuscript as well as their fruitful comments and suggestions. We have taken all of them into account in the revised version.
With best regards,
Dr. Brigitte Leridon,
on behalf of all authors.
List of changes
We have added the information on the different materials in the introduction paragraph (and added subsequent references). We have reformulated the sentence about spin fluctuations,
in order to avoid ambiguity.
We have added references to Dr. Phillips' work [57,58].
We have also added a full paragraph discussing the differences between cuprate families in relation to our findings just before the conclusion.
The changes are printed in red in the revised version.
