Title: Epitaxial growth of iridate pyrochlore Nd₂Ir₂O₇ films

Abstract

Epitaxial films of the pyrochlore Nd₂Ir₂O₇ have been grown on (111)-oriented yttria-stabilized zirconia (YSZ) substrates by off-axis sputtering followed by post-growth annealing. X-ray diffraction (XRD) results demonstrate phase-pure epitaxial growth of the pyrochlore films on YSZ. Scanning transmission electron microscopy (STEM) investigation of an Nd₂Ir₂O₇ film with a short post-annealing provides insight into the mechanism for crystallization of Nd₂Ir₂O₇ during the post-annealing process. STEM images reveal clear pyrochlore ordering of Nd and Ir in the films. As a result, the epitaxial relationship between the YSZ and Nd₂Ir₂O₇ is observed clearly while some interfacial regions show a thin region with polycrystalline Ir nanocrystals.

Epitaxial thin films of pyrochlore iridate Bi_2+xIr_2-yO_7-δ: structure, defects and transport properties

Journal Article Yang, W. C. ; Xie, Y. T. ; Zhu, W. K. ; ... - Scientific Reports

While pyrochlore iridate thin films are theoretically predicted to possess a variety of emergent topological properties, experimental verification of these predictions can be obstructed by the challenge in thin film growth. We report on the pulsed laser deposition and characterization of thin films of a representative pyrochlore compound Bi₂Ir₂O₇. Moreover, the films were epitaxially grown on yttria-stabilized zirconia substrates and have lattice constants that are a few percent larger than that of the bulk single crystals. The film composition shows a strong dependence on the oxygen partial pressure. Density-functional-theory calculations indicate the existence of BiIr antisite defects, qualitatively consistent withmore »« less

Spontaneous Hall effect enhanced by local Ir moments in epitaxial Pr₂Ir₂O₇ thin films

Journal Article Guo, Lu ; Campbell, Neil ; Choi, Yongseong ; ... - Physical Review B

Rare-earth pyrochlore iridates (RE₂Ir₂O₇) consist of two interpenetrating cation sublattices, the RE with highly frustrated magnetic moments, and the iridium with extended conduction orbitals significantly mixed by spin-orbit interactions. The coexistence and coupling of these two sublattices create a landscape for discovery and manipulation of quantum phenomena such as the topological Hall effect, massless conduction bands, and quantum criticality. Thin films allow extended control of the material system via symmetry-lowering effects such as strain. While bulk Pr₂Ir₂O₇ shows a spontaneous hysteretic Hall effect below 1.5 K, we observe the effect at elevated temperatures up to 15 K in epitaxial thinmore »« less

Abstract The synthesis of fully epitaxial ferroelectric Hf _0.5 Zr _0.5 O ₂ (HZO) thin films through the use of a conducting pyrochlore oxide electrode that acts as a structural and chemical template is reported. Such pyrochlores, exemplified by Pb ₂ Ir ₂ O ₇ (PIO) and Bi ₂ Ru ₂ O ₇ (BRO), exhibit metallic conductivity with room‐temperature resistivity of <1 mΩ cm and are closely lattice matched to yttria‐stabilized zirconia substrates as well as the HZO layers grown on top of them. Evidence for epitaxy and domain formation is established with X‐ray diffraction and scanning transmission electron microscopy,more »« less

Possible scale invariant linear magnetoresistance in pyrochlore iridates Bi₂Ir₂O₇

Journal Article Chu, Jiun-Haw ; Liu, Jian ; Zhang, Han ; ... - New Journal of Physics

We report the observation of a linear magnetoresistance in single crystals and epitaxial thin films of the pyrochlore iridate Bi₂Ir₂O₇. The linear magnetoresistance is positive and isotropic at low temperatures, without any sign of saturation up to 35 T. As temperature increases, the linear field dependence gradually evolves to a quadratic field dependence. The temperature and field dependence of magnetoresistance of Bi₂Ir₂O₇ bears strikingly resemblance to the scale invariant magnetoresistance observed in the strange metal phase in high Tc cuprates. However, the residual resistivity of Bi₂Ir₂O₇ is more than two orders of magnitude higher than the curpates. Our results suggestmore »« less

Fabrication of High Current YBa₂Cu₃O(sub>7-y) Coated Conductors Using Rolling-Assisted Biaxially Textured Substrates

Conference Christen, D K ; Feenstra, R ; Kroeger, D M ; ...

High critical current YBa₂Cu₃O_7-y (referred to as YBCO) coated conductors were fabricated with a layer sequence of YBCO/YSZ/CeO₂/Ni. The cube (100) texture in the starting Ni substrates was obtained by cold rolling followed by recrystallization. A thin CeO₂ (Cerium Oxide) layer with a thickness of 100-200 Å was grown epitaxially on the biaxially textured-Ni substrates using an e-beam evaporation technique. This was followed by the growth of a thick (<= 0.77 µm) YSZ (Yttria Stabilized Zirconia) layer using either e-beam evaporation or rf magnetron sputtering. The e-beam CeO₂ film had a dense microstructure. The microstructure of the e-beam YSZ filmmore »« less
