Resumen

We have performed vibrating reed (f≈1 kHz) and ac susceptibility (f-800 kHz, i.e. RF penetration depth) measurements on superconducting 2H-NbSe₂ and 2H-NbS₂ in magnetic fields. For NbSe₂, a low temperature dissipation peak is correlated with a dip in vibrating reed resonant frequency and peak in ac susceptibility, signifying softening of the flux line lattice: these features are not observed in NbS₂. We suggest that the softening of the FLL is due to an interaction with the CDW, which does not occur in NbS₂.
