Progress on photoemission studies of nodal plane in LaNiGa₂

LaNiGa₂ is a time-reversal-symmetry-breaking superconductor below 2K. Recently, large platelet-style single crystal specimens have clarified the space group for the crystal structure which in turn predicts a novel electronic structure with Fermi surface degeneracies on one plane of the Brillouin zone. While the large platelet face of the crystals is most accessible to photoemission studies, the predicted degeneracies are on a plane orthogonal to the platelet face, making it difficult to probe with angle resolved photoemission spectroscopy (ARPES). In this talk we will present progress on accessing the predicted electronic degeneracies in LaNiGa2 directly with ARPES.
