Abstract
A vortex phase diagram of the strongly correlated superconductor Rh17S15 has been constructed via exploration of the anomalous variations in critical current density extracted from ac and dc magnetization measurements. The isofield in-phase ac susceptiblity data reveal the presence of multiple steps at different fields. The dc magnetisation hysteresis loops show the presence of a very broad fishtail commencing deep inside the mixed state and lasting upto Hc2. We have also analysed the scan rate dependence of the hysteresis width in the vibrating sample magnetometer data with a view to distinguish between the different possible order-disorder transformations in the flux line lattice.
