Abstract

The normal-state transport properties of La1.85-xSr 0.15+xCu1-xAlxOy system have been investigated by means of resistivity and thermoelectric power. The structural analysis indicates that with the increase of x, both the lattice parameter a and c decrease. An MI transition appears with Al doping. Al doping partly perturb the periodic potential of the system, thus producing a weakly temperature dependent TEP. The different effect of doping between Al and other transition metal is discussed.
