抄録

Two components of current-induced electric fields in ab plane, Ex and Ey, have been measured simultaneously on YBCO(123) films around the glass transition temperature Tg in magnetic fields H with components (H0, H0, 0.1H0), where x and y axes are parallel to the direction of the current density and c axis, respectively. In this condition, a finite transverse field Ey almost equal to Ex can be observed if the vortex lines form and move along the Lorentz force. In each H, the ratio |Ey/Ex| at a low current limit, which is zero far above Tg, increases in the critical region and transfers to unity below Tg. Our results indicate that the vortices become lines with long range correlation along H direction at the vortex glass transition without receiving the effect of the intrinsic pinning.
