Systematic Evolution of the Magnetotransport Properties of Bi_{2}Sr_{2-x}La_{x}CuO_{6} with Carrier Concentration


الملخص بالإنكليزية

We report that it is possible to obtain a series of high-quality crystals of La-doped Bi-2201, of which the transport properties have been believed to be dirtier than those of other cuprates. In our crystals, the normal-state transport properties display behaviors which are in good accord with other cuprates; for example, in the underdoped region the in-plane resistivity rho_{ab} shows the pseudogap feature and in the overdoped region the T dependence of rho_{ab} changes to T^n with n > 1. The characteristic temperatures of the pseudogap deduced from the resistivity and the Hall coefficient data are presented.
