Abstract: From systematic analysis of the high pulsed magnetic field resistance data of LaSr CuO 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 and 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 and and the characteristic temperature for the onset of the competing charge density wave phase is found to vanish above . At the two phases are found to coexist exactly at zero magnetic field.
