|Abstract: ||A comparative study of the thermomagnetic memory effects of J(c) in two weakly pinned low T-c superconductors, Ca3Rh4Sn13 (CaRhSn) and Yb3Rh4Sn13 (YbRhSn), is presented. In both the systems, the peak effect (PE) phenomenon appears as an order-disorder transformation through stepwise amorphization of the flux line lattice (FLL). However, in CaRhSn, we can witness another disorder-driven transition (Bragg glass (BG) to a vortex glass (VG)) in a distinct manner as in a single crystal of high T, YBa2Cu3O7-delta for Hparallel toc.|
