Sažetak
The out-of-plane magnetoresistance (MR) of single crystals of La2−xSrxCuO4 has been measured over a wide doping range (0.09<~x<~0.25) with the field applied parallel and perpendicular to the CuO2 planes. Surprisingly, the longitudinal c-axis MR (I∥c, B∥c) is always larger (i.e., more positive) than the transverse MR (I∥c, B∥ab) for all doping concentrations. In addition, for optimally doped and overdoped samples, the longitudinal c-axis MR follows the same temperature dependence as the in-plane transverse MR (I∥ab, B∥c). These observations suggest that c-axis transport in La2−xSrxCuO4 is an incoherent process whereby the carriers undergo significant scattering within the plane before hopping to an adjacent layer.
