D. Lopez et al., AMPLIFICATION OF THE C-AXIS VORTEX CORRELATION BY TWIN-BOUNDARY PINNING AT THE VORTEX LIQUID-SOLID PHASE-TRANSITION, Physical review. B, Condensed matter, 53(14), 1996, pp. 8895-8897
Transport measurements using the dc flux transformer configuration tog
ether with c-axis resistance data in clean and twinned YBa2Cu3O7-delta
single crystals show that vortices are localized by the twin-boundary
potential. The results support the existence of a divergent tilt modu
