✦ Synopsis

Transport properties of Bi2_xPbxCa2Sr2Cu30y (x=0, 0.2, 0.4 and 0.6) were investigated by means of measuring Hall coefficient between Tc up £o 300K.

The experimental results show that the carrier density n H is linearly T-dependent, e.g. the formula nx(T)=n o (l+aT) is well satlsified in normal state, n H decreases intensely with increasing Pb content, and does not vary with the magnetic fields.

The results are compared with a recent theoretical calculation.
