Phys. Rev. Lett. 79, 139–142 (1997)Steric Repulsion and van der Waals Attraction between Flux Lines in Disordered High Tc SuperconductorsReceived 16 December 1996; published in the issue dated 7 July 1997 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)]. © 1997 The American Physical Society URL:
