Evidence of surface superconductivity and multi-quanta vortex states in a weakly-pinned single crystal of Ca3Ir4Sn13
Santosh Kumar, Ravi P. Singh, A. Thamizhavel +2
We report here the observation of anomalous paramagnetic signal(s) in the isofield field-cooled cool-down magnetization scans (MFCC(T)) recorded for a single crystal of a low Tc su…
Dual role of an ac driving force and the underlying two distinct order-disorder transitions in the vortex phase diagram of Ca3Ir4Sn13
Santosh Kumar, Ravi P. Singh, A. Thamizhavel +2
We present distinct demarcation of the Bragg glass (BG) to multi-domain vortex glass (VG) transition line and the eventual amorphization of the VG phase in a weakly pinned single c…
Effect of nominal substitution of transition metals for excess Fe in Fe_{1+x}Se superconductor
Anil K Yadav, Santosh Kumar, Anup V Sanchela +2
Taking cue from the increase in the superconducting transition temperature (Tc) of Fe1+xSe via nominal (2 wt%) substitution of Cr instead of excess Fe, we have now extended our stu…
