We observe dispersing magnons only in the capped samples, progressively dampened at higher doping. We detect an elastic resonant scattering peak in the uncapped compound at wave vector (\u223c1\/3,0), remindful of the charge order signal in hole doped cuprates. The peak weakens at x=0.05 and disappears in the superconducting x=0.20 film. The role of the capping on the electronic reconstruction far from the interface remains to be understood.<\/p>\n\n\n\n<p><a href=\"https:\/\/journals.aps.org\/prl\/abstract\/10.1103\/PhysRevLett.129.027002\">Phys.
