Sažetak
We present Hall effect measurements in the normal state of the high temperature superconducting ceramics La2−xSrxCuO4 (x = 0, 0.05, 0.08, 0.1, 0.15, 0.2, 0.25 and 0.30). The Hall constant (RH) is positive and it is a decreasing function of x.Every Sr gives not, vert, similar 1 hole to the conduction band. For x = 0 RH has semiconductor-like temperature dependence, while for the other Sr concentration RH is constant in temperature. The Hall mobility (/uH) decreases with x at high temperatures. For x = 0 d /uH/dT > 0 and with doping it changes to d/uH/dT<0. We give a simple model calculation which qualitatively accounts for the observed behaviour of the resistivity, Hall constant and Hall mobility as a function of Sr concentration.
