Title: Orbital-and spin-driven lattice instabilities in quasi-one-dimensional CaV₂O₄

Abstract

Here, calcium vanadate CaV₂O₄ has a crystal structure of quasi-one-dimensional zigzag chains composed of orbital-active V³⁺ ions and undergoes successive structural and antiferromagnetic phase transitions at T_s~140 K and T_N~70 K, respectively. We perform ultrasound velocity measurements on a single crystal of CaV₂O₄. The temperature dependence of its shear elastic moduli exhibits huge Curie-type softening upon cooling that emerges above and below T_s depending on the elastic mode. The softening above T_s suggests the presence of either onsite Jahn-Teller-type or intersite ferrotype orbital fluctuations in the two inequivalent V³⁺ zigzag chains. The softening below T_s suggests the occurrence of a dimensional spin-state crossover, from quasi-one to three, that is driven by the spin-lattice coupling along the inter-zigzag-chain orthogonal direction. The successive emergence of the orbital- and spin-driven lattice instabilities above and below T_s, respectively, is unique to the orbital-spin zigzag chain system of CaV₂O₄.

Single-crystal growth, crystallography, magnetic susceptibility, heat capacity, and thermal expansion of the antiferromagnetic S=1 chain compound CaV[subscript 2]O[subscript 4]

Journal Article Niazi, A ; Bud'ko, S L ; Schlagel, D L ; ... - Phys. Rev. B

The compound CaV{sub 2}O{sub 4} contains V{sup +3} cations with spin S=1 and has an orthorhombic structure at room temperature containing zigzag chains of V atoms running along the c axis. We have grown single crystals of CaV{sub 2}O{sub 4} and report crystallography, static magnetization, magnetic susceptibility x, ac magnetic susceptibility, heat capacity C{sub p}, and thermal expansion measurements in the temperature T range of 1.8--350 K on the single crystals and on polycrystalline samples. An orthorhombic-to-monoclinic structural distortion and a long-range antiferromagnetic (AF) transition were found at sample-dependent temperatures T{sub S}{approx}108--145 K and T{sub N}{approx}51--76 K, respectively.

Correlation Effects and Hidden Spin-Orbit Entangled Electronic Order in Parent and Electron-Doped Iridates ${Sr}_{2} {IrO}_{4}$

Journal Article Zhou, Sen ; Jiang, Kun ; Chen, Hua ; ... - Physical Review. X

Analogs of the high-T_c cuprates have been long sought after in transition metal oxides. Because of the strong spin-orbit coupling, the 5d perovskite iridates Sr₂IrO₄ exhibit a low-energy electronic structure remarkably similar to the cuprates. Whether a superconducting state exists as in the cuprates requires understanding the correlated spin-orbit entangled electronic states. Recent experiments discovered hidden order in the parent and electron-doped iridates, some with striking analogies to the cuprates, including Fermi surface pockets, Fermi arcs, and pseudogap. Here, we study the correlation and disorder effects in a five-orbital model derived from the band theory. We find that the experimentalmore »« less

We examine nuclear spin-lattice relaxation rates (1/{ital T}{sub 1}) at copper (Cu), oxygen (O), and yttrium (Y) sites in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}. We use a two-hole band model consisting of strongly Heisenberg superexchange coupled spins ({ital S}=1/2) on Cu sites that are exchange coupled with strength {ital J}{sub {ital p}{ital d}} to itinerant oxygen holes introduced by doping. The Cu(1) (chain) spins are modeled by one-dimensional Heisenberg chains; the Cu(2) (planar) spins are modeled by two-dimensional Schwinger boson mean-field theory.
