| Abstract(in English) | We measured voltages across micro-bridges fabricated along the c axis of La_<2-x>Sr_xCuO_4 single crystals as a function of the angle between an applied magnetic field and the ab plane. A remarkable voltage appeared when the magnetic field was aligned to the ab plane within a few degrees.The voltage measured at low temperature(<10K)in the fields(<1.5T)was induced by moving vortices, and did not relate to any other dissipative process such as superconducting fluctuation.The vortex velocity estimated from the maximum voltage is much lower than that of Bi_2Sr_2CaCu_2O_δ single crystals.We may consider that many weak point-like pinning centers are in the crystals, because the angular dependence of the voltage can be explained by the collective flux creep model. |
