Abstract
CeRu2 and 2H-NbSe2 display remarkable similarities in their magnetic r esponse, reflecting the manner in which the weakly pinned flux link la ttice (FLL) loses spatial order in the peak-effect (PE) regime. We pre sent evidence for discontinuous changes in the screening response near the onset of the PE in these systems, and demonstrate history-depende nt effects. We attribute these features to a disorder-induced fracturi ng and entanglement of the FLL, as an alternative to the appearance of a spatially modulated ground state for CeRu2.
