Sažetak
We report Hall-effect measurements in the slowly cooled and quenched states of ABa2Cu3O7−δ, A=Y, Gd. The slowly cooled sample is superconducting at T=90K. The Hall constant (RH) is of the order of 10−9m3/C, corresponding to ≈ 1 hole per unit cell at 300K. Unusually for metals, RH increases on decreasing temperature. Quenched from 750°C to room temperature the sample is semiconductor at least down to 4.2K. RH is increased ≈ 20 times with respect to the slowly cooled sample, with activated temperature dependence.
