Singular angular magnetoresistance and sharp resonant features in a high-mobility metal with open orbits, ReO3
Nicholas P. Quirk, Loi T. Nguyen, Jiayi Hu +2
We report high-resolution angular magnetoresistance (AMR) experiments performed on crystals of ReO with high mobility (90,000 cm/Vs at 2 K) and extremely low residual resis…
NbIrB and TaIrB -- new low symmetry noncentrosymmetric superconductors with strong spin orbit coupling
Karolina Górnicka, Xin Gui, Bartlomiej Wiendlocha +4
Superconductivity was first observed more than a century ago, but the search for new superconducting materials remains a challenge. The Cooper pairs in superconductors are ideal em…
Van der Waals Heterostructure Magnetic Josephson Junction
H. Idzuchi, F. Pientka, K. -F. Huang +9
When two superconductors are connected across a ferromagnet, the spin configuration of the transferred Cooper pairs can be modulated due to magnetic exchange interaction. The resul…

Ba2CaMoO6 was synthesized by solid state method. The crystal structure adopts cubic Fm-3m space group at room temperature with lattice parameters of 8.378231(5) {angstroms}. Upon c…
Structure, Magnetism and First Principles Modeling of the Na0.5La0.5RuO3 Perovskite
Loi T. Nguyen, Matthieu Saubanère, Robert J. Cava
High purity polycrystalline Na0.5La0.5RuO3 was synthesized by a solid state method, and its properties were studied by magnetic susceptibility, heat capacity and resistivity measur…
Widely Spaced Planes of Magnetic Dimers in the Ba6Y2Rh2Ti2O17-δ Hexagonal Perovskite
Loi T. Nguyen, Daniel B. Straus, Q. Zhang +1
We report the synthesis and initial characterization of Ba6Y2Rh2Ti2O17-δ, a previously unreported material with a hexagonal symmetry structure. Face-sharing RhO6 octahedra form tri…
Hexagonal Perovskites as Quantum Materials
Loi T. Nguyen, R. J. Cava
Hexagonal oxide perovskites, in contrast to the more familiar perovskites, allow for face-sharing of metal-oxygen octahedra or trigonal prisms within their structural frameworks. T…
Long-range and local crystal structures of the Sr1-xCaxRuO3 Perovskites
