| Abstract(in English) | Resistivity measurements of the bulk material of La_2-X>Sr_XCuO_ 4 revealed the following phenomena.(a)The x dependence of the resistivity ρ(x)shows remarkable decrease at x【approximately equa l】1, 4^N(N=1,2,3,...).The decrease is observed from low temperatur e up to room temperature.(b)The superconductivity appears at low temperature in the doping range 1/4^2【less than or equal】x【less than or equal】1/4.In order to investigate the resistivity decrease phenomenon,we conducted the measurement of Hall effect on bulk and film samples of La_2-X>Sr_XCuO_4,and found that the carrier mobility clearly increases around the doping level noted above. |
