Formation of vortex line around the glass transition in YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} films
- Chiba Univ., Inageku (Japan)
Two components of current-induced electric fields in ab plane, E{sub x} and E{sub y}, have been measured simultaneously on YBCO(123) films around the glass transition temperature T{sub g} in magnetic fields H with components (H{sub 0}, H{sub 0}, 0.1H{sub 0}), 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 E{sub y} almost equal to E{sub x} can be observed if the vortex lines form and move along the Lorentz force. In each H, the ratio {vert_bar}E{sub y}/E{sub x}{vert_bar} at a low current limit, which is zero far above T{sub g}, increases in the critical region and transfers to unity below T{sub g}. The authors 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.
