Nematic Ising superconductivity with hidden magnetism in few-layer 6R-TaS₂.

ABSTRACT: In van der Waals heterostructures (vdWHs), the manipulation of interlayer stacking/coupling allows for the construction of customizable quantum systems exhibiting exotic physics. An illustrative example is the diverse range of states of matter achieved through varying the proximity coupling between two-dimensional (2D) quantum spin liquid (QSL) and superconductors within the TaS₂ family. This study presents a demonstration of the intertwined physics of spontaneous rotational symmetry breaking, hidden magnetism, and Ising superconductivity (SC) in the three-fold rotationally symmetric, non-magnetic natural vdWHs 6R-TaS₂. A distinctive phase emerges in 6R-TaS₂ below a characteristic temperature (T^*) of approximately 30 K, which is characterized by
