Possible Superconducting Phase in Janus Transition Metal Dichalcogenide TiSeS

Recently, transition metal dichalcogenides (TMD) have attracted a lot of attention because they can host a number of novel phases, including charge density wave and topological superconductivity. This class of compounds is significant from application and fundamental standpoints. Here we report on the synthesis and characterization of Janus TMD compound TiSeS, which is a subclass of TMDs. We observe characters of filamentary superconductivity in TiSeS, which was not reported in earlier studies. Magnetization measurements (ZFCW& FCW) as well as isothermal magnetization indicates towards type-II superconductivity whereas transport measurements lacks of zero resistivity due to possible weak inter-grain connectivity. The observed behavior can be safely attributed to filamentary superconductivity in TiSeS. Further studies need to be carried out to determine the origin of this superconducting phase.
