  In this article, we report the detailed magneto transport measurements of the
topological semimetal (TSM) candidate, Sn2Pd. Single crystal of Sn2Pd is
synthesized through the self-flux method. Phase purity and crystalline
morphology are confirmed through powder X ray diffraction (PXRD) pattern and
field emission scanning electron microscopy (FESEM) image. Signatures of
superconducting transition are seen in both transport and magneto transport
measurements, which are further supported by the AC magnetization studies.
Sn2Pd is found to show superconductivity onset at below 2.8K, but not the zero
resistivity down to 2K. Although, isothermal magneto resistivity measurements
below superconducting onset (2.8K) clearly exhibited superconductor-like
behavior, but is not observed in heat capacity measurements, indicating the
same to be of weak nature. Magnetotransport measurements performed in a normal
state of Sn2Pd show the presence of a weak antilocalization (WAL) effect, which
is confirmed by modeling of low field magneto-conductivity (MC) through Hikami
Larkin Nagaoka (HLN) formalism. Here, it is worth mentioning that the present
article is the first report on magneto transport measurements of Sn2Pd, which
show the same to be a topological material with a weak superconducting phase
below around 2.8K.
