Spectroscopic evidence of multi-gap superconductivity in non-centrosymmetric AuBe

Soumya Datta, Aastha Vasdev, Partha Sarathi Rana +5

AuBe is a chiral, non-centrosymmetric superconductor with transition temperature 3.25 K. The broken inversion symmetry in its crystal structure makes AuBe a possible…

Spectroscopic evidence of mixed angular momentum symmetry in non-centrosymmetric RuB

Soumya Datta, Aastha Vasdev, Ranjani Ramachandran +7

Superconducting crystals with lack of inversion symmetry can potentially host unconventional pairing. However, till date, no direct conclusive experimental evidence of such unconve…

Unveiling of Bragg glass to vortex glass transition by an ac driving force in a single crystal of Yb3Rh4Sn13

Santosh Kumar, Ravi P. Singh, A. Thamizhavel +2

We present here some striking discrepancies in the results of ac and dc magnetization measurements performed in a single crystal of low Tc superconductor, Yb3Rh4Sn13. Fingerprint o…

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…
