First-order phase transition from the vortex liquid to an amorphous solid
Physical review letters, 2003•APS
We present a systematic study of the topology of the vortex solid phase in superconducting B
i 2 S r 2 C a C u 2 O 8 samples with low doses of columnar defects. A new state of vortex
matter imposed by the presence of geometrical contours associated with the random
distribution of columns is found. The results show that the first-order liquid-solid transition in
this vortex matter does not require a structural symmetry change.
