Abstract ： The transport properties of underdoped YBa2 Cu3 Ox (YBCO) crystals with x = 6.95, 6.80, 6.66 were measured and the effect of pseudogap on the Hall conductivity was studied. In the normal state, the Hall angle remains unperturbed at the crossover temperature of resistivity for the underdoped samples. An anomalous suppression of the vortex Hall current was observed near Tc and the contribution of the vortices to the Hall current is absent above 4K in 6K YBCO (x = 6.66).
