Title: Spin glass behavior in frustrated quantum spin system CuAl ₂ O ₄ with a possible orbital liquid state

Abstract

CuAl₂O₄ is a normal spinel oxide having quantum spin, S = 1/2 for Cu²⁺. It is a rather unique feature that the Cu²⁺ ions of CuAl₂O₄ sit at a tetrahedral position, not like the usual octahedral position for many oxides. At low temperatures, it exhibits all the thermodynamic evidence of a quantum spin glass. For example, the polycrystalline CuAl₂O₄ shows a cusp centered at ~2 K in the low-field dc magnetization data and a clear frequency dependence in the ac magnetic susceptibility while it displays logarithmic relaxation behavior in a time dependence of the magnetization. At the same time, there is a peak at ~2.3 K in the heat capacity, which shifts towards a higher temperature with magnetic fields. Conversely, there is no evidence of new superlattice peaks in the high-resolution neutron powder diffraction data when cooled from 40 to 0.4 K. This implies that there is no long-ranged magnetic order down to 0.4 K, thus confirming a spin glass-like ground state for CuAl₂O₄. Interestingly, there is no sign of structural distortion either although Cu²⁺ is a Jahn–Teller active ion. Therefore, we claim that an orbital liquid state is the most likely ground state in CuAl₂O₄.

Magnetic and structural properties of the solid solution CuAl_2(1–x)Ga_2xO₄

Journal Article Bullard, Thomas J. ; Susner, Michael A. ; Taddei, Keith M. ; ... - Scientific Reports

CuAl₂O₄ is a ternary oxide spinel with Cu²⁺ ions (s = 1/2) primarily populating the A-site diamond sublattice. The compound is reported to display evidence of spin glass behavior but possess a non-frozen magnetic ground state below the transition temperature. On the other hand, the spinel CuGa₂O₄ displays spin glass behavior at ~ 2.5 K with Cu²⁺ ions more readily tending to the B-site pyrochlore sublattice. Therefore, we investigate the magnetic and structural properties of the solid solution CuAl_2(1-x)Ga_2xO₄ examining the evolution of the magnetic behavior as Al³⁺ is replaced with a much larger Ga³⁺ ion. Our results show thatmore »« less

Evolution of spin phonon coupling by substituting Cd for Zn in the frustrated spinel ZnCr{sub 2}Se{sub 4}

Frustration makes a tremendous amount of degenerate ground states which provides no energy scale of its own. Any perturbation has to be considered strong and fascinating phenomena may be emergent upon relieving of frustration. Here, we report the evolution of spin phonon coupling in the frustrated spinel system Zn{sub 1−x}Cd{sub x}Cr{sub 2}Se{sub 4} (0 ≤ x ≤ 1) from magnetization, specific heat and thermal conductivity. Our results give clear evidences that the spin-orientated structural transitions decay rapidly as x going from 0 to 0.4 while the correlations between spin and lattice degrees of freedom for 0.6 ≤ x ≤ 1more »« less

The discovery of delafossite compound has encouraged more rapid technological developments particularly in transparent electronic devices. Copper oxide-based transparent thin films delafossite semiconductor recently give much attention in the field of optoelectronic technology, after the discovery of p-type CuAlO{sub 2}. The potential applications of a p-type semiconductor transparent conductive oxides (TCO) have been applied in broad field of optoelectronics. To explore a broad physical properties interms of magnetic conducting subtitution is understudied.

Journal Article Ge, L. ; Flynn, J. ; Paddison, Joseph A. M. ; ... - Physical Review B

Here, antiferromagnetic insulators on a diamond lattice are candidate materials to host exotic magnetic phenomena ranging from spin-orbital entanglement to degenerate spiral ground states and topological paramagnetism. Compared to other three-dimensional networks of magnetic ions, such as the geometrically frustrated pyrochlore lattice, the investigation of diamond-lattice magnetism in real materials is less mature. In this work, we characterize the magnetic properties of model A-site spinels CoRh₂O₄ (cobalt rhodite) and CuRh₂O₄ (copper rhodite) by means of thermomagnetic and neutron-scattering measurements, and we perform group theory analysis, Rietveld refinement, mean-field theory, and spin-wave theory calculations to analyze the experimental results.

Nature of copper active sites in the carbon monoxide oxidation on CuAl{sub 2}O{sub 4} and CuCr{sub 2}O{sub 4} spinel type catalysts

Journal Article Severino, F ; Brito, J L ; Laine, J ; ... - Journal of Catalysis

Unsupported copper-aluminum and copper-chromium oxides were prepared by mixing solutions of the nitrates and calcining at 1223 K, followed by treatment with washing solutions of either ammonium carbonate or nitric acid in order to extract uncombined copper oxide. Ammonium carbonate was only effective for removal of dispersed CuO, whereas nitric acid removed both dispersed a/nd crystalline CuO. Catalyst activity for CO oxidation increased with the extraction treatments, particularly with the nitric acid washing solution, indicating that the active sites are copper species derived from CuAl{sub 2}O{sub 4} and CuCr{sub 2}O{sub 4} spinels rather than from CuO.
