Resumen:
The first-order transition (FOT) in Bi 2 Sr 2 CaCu 2 O 8+δ vortex matter with a moderate dosis of columnar defects (CD) was studied with Hall probemagnetometry. The vortex phase diagram for matching fields of 10, 30 and60 Gauss are compared. We measure the entropy-jump at the FOT in samples with CD and compare with previous data of pristine samples.
