Transport properties of superconducting misfit layered compound — •Tarushi Agarwal, Chandan Patra, Poulami Manna, Shashank Srivastava, Priya Mishra, Suhani Sharma, and Ravi Prakash Singh — Indian Institute of Science Education & Research Bhopal

Misfit layered compounds, naturally occurring bulk heterostructures, present a compelling alternative to artificially engineered ones, offering a unique platform for exploring correlated phases and quantum phenomena. This study investigates the magnetotransport and superconducting properties of the misfit compound (PbS)_1.13TaS₂, comprising alternating PbS and 1H-TaS₂ layers. It exhibits distinctive transport properties, including a prominent planar Hall effect and a fourfold oscillatory anisotropic magnetoresistance. Moreover, it shows multigap 2D superconductivity with a high in-plane upper critical field, exceeding the Pauli limit. The coexistence of multigap superconductivity and anomalous transport within the same material firmly positions misfit compounds as an ideal platform for realizing quantum effects in the two-dimensional limit of bulk crystals. This opens the door to the development of quantum devices with less complexity and enhanced tunability.
