| 概要 | The temperature dependence of the Hall coefficient is measured with high accuracy in a series of YBa2(Cu1-zZnz)3O6.78 crystals with 0 <
-z < -0.013. We found that the cotangent of the Hall angle, cot θH, starts to deviate upward from the T2 dependence below T0(130K), regardless of the Zn concentration. We discuss that this deviation is caused by the pseudogap the direction of the deviation and its insensitivity to the Zn doping suggest that the pseudogap affects cotθH through a change in the effective mass, rather than through a change in the Hall scattering rate. © 1999 American Physical Society. |
