Observation of two critical current densities in a weakly pinned single crystal of $Ca3Rh4Sn13$

We present the dc magnetization measurements in a weakly pinned single crystal of $Ca3Rh4Sn13$ (T_c ≈ 8.35 K). In this particular sample we noticed that the sweep field mode magnetization data are not matching with the stable field mode magnetization data. Here we provide the evidence of existence of two critical current densities probably related to the existence of two different vortex lattice structure configurations inside the crystal.
