Magnetically Charged Superdomain Walls In Square Artificial Spin Ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report direct evidence that magnetically charged superdomain walls form spontaneously in two dimensional square artificial spin ice nanostructures in response to external magnet…
New Evidence for a Low-Temperature Magnetic Ground State in Double-Perovskite Iridates with Ir5+(5d4) Ions
J. Terizc, H. Zheng, Feng Ye +4
We report an unusual magnetic ground state in single-crystal, double-perovskite Ba2YIrO6 and Sr doped Ba2YIrO6 with Ir5+(5d4) ions. Long-range magnetic order below 1.7 K is confirm…
Anisotropic electronic properties of a-axis-oriented Sr2IrO4 epitaxial thin-films
J. Nichols, O. B. Korneta, J. Terzic +4
We have investigated the transport and optical properties along the c-axis of a-axis-oriented Sr2IrO4 epitaxial thin-films grown on LaSrGaO4 (100) substrates. The c-axis resistivit…
Lattice-Driven Magnetoresistivity and Metal-Insulator Transition in Single-Layered Iridates
M. Ge, T. F. Qi, O. B. Korneta +4
Sr2IrO4 exhibits a novel insulating state driven by spin-orbit interactions. We report two novel phenomena, namely a large magnetoresistivity in Sr2IrO4 that is extremely sensitive…
Electron-Doped Sr2IrO4-delta (0 <= delta <= 0.04): Evolution of a Disordered Jeff = 1/2 Mott Insulator into an Exotic Metallic State
O. B. Korneta, Tongfei Qi, S. Chikara +3
Stoichiometric Sr2IrO4 is a ferromagnetic Jeff = 1/2 Mott insulator driven by strong spin-orbit coupling. Introduction of very dilute oxygen vacancies into single-crystal Sr2IrO4-d…
Crystal Structure and Physical Properties of U3T3Sn4 (T = Ni, Cu) Single-Crystals
L. Shlyk, P. Estrela, J. C. Waerenborgh +5
Heat capacity experiments, crystal structure determination and transmission electron microscopy have been carried out on U3Cu3Sn4 single-crystals. U3Cu3Sn4 was confirmed to be a he…
