Proximity effects of 2D antiferromagnets on superconductivity in exfoliated niobium disulfide

The conventional theory of superconductivity holds that Cooper pairs form due to electron–phonon coupling; however, this description may not be adequate describe certain unconventional superconductors such as cuprates and iron chalcogenides. In these superconductors, it has been proposed spin fluctuations responsible for the formation pairs. study, we explore interactions in transition metal, dichalcogenide niobium disulfide, induced through proximity effects by fabricating antiferromagnet/NbS2 heterostructures. We tested three different 2D antiferromagnetic materials, each with textures: anganese phosphorus trisulfide, manganese triselenide, chromium trichloride. Our results showed a substantial reduction critical temperature case NbS2/MnPSe3. hypothesize could MnPSe3 inducing NbS2.
