| Abstract: |
The origin of the Hall sign reversal in the cuprates superconductors is an open question for more than 30 years, dating back to the discovery of the cuprates. This phenomenon has many theoretical explanations which attribute the sign change to different effects in the rich phase diagram of the cuprates. In this talk I will present our Hall data in pristine and Zn substituted thin films of Bi2212. Using Zn substitution we decouple the critical temperature from the doping level of the films, in order to distinguish between the role of the different phases in determining the sign of the Hall resistance |
