Abstract
We show that in anisotropic or layered superconductors impurities induce a van der Waals attraction between flux lines. This attraction together with the disorder induced repulsion may change the low- B–low- T phase diagram significantly from that of the pure thermal case considered recently by G. Blatter and V. Geshkenbein [Phys. Rev. Lett. 77, 4958 (1996)].
