Abstract
The screening response of the kagome superconductor CsV3Sb5 was obtained from high-resolution ac mutual inductance measurements. At zero applied magnetic field and low temperatures, we observe no evidence for gapless quasiparticles, while near Tc we find evidence for enhanced fluctuations. A rich vortex state appears above Hc1≈30 Oe, exhibiting successive emergence of vortex phases. For a fixed magnetic field, lowering the temperature below Tc(H) leads to a wide range of vortex liquid state in a landscape of weak pinning potential, which gives rise to an irreversibility line. Further lowering the temperature, we identify the vortex melting line followed by the peak effect manifested in enhanced vortex pinning strength and critical current. We suggest that such an unusual behavior, where the peak effect region is fully contained within the vortex lattice state below the irreversibility line, is a consequence of the strong anisotropy and weak bulk pinning in CsV3Sb5.
