Title: Revealing the pseudogap in Sr₃(Ru_0.985Fe_0.015)₂O₇ by optical spectroscopy

Abstract

We report resistivity, magnetization, and optical spectroscopy study on single-crystal sample of Sr₃(Ru_0.985Fe_0.015)₂O₇. An upturn is observed in resistivity at about 30 K. Below 30 K, the dip in resistivity R(ω), the suppression in scattering rate 1/τ(ω), the peaklike feature in optical conductivity σ₁(ω), and the remainder of spectral weight all suggest the formation of a pseudogap. In addition, one phonon peak at about 600cm^–1 is distinguished at all temperatures, which has asymmetric line shape. Such asymmetric line shape can be fit by a Fano function, and the resulting Fano factor 1/q² and linewidth γ show significant increases below 30 K, giving further evidence for the formation of a pseudogap, which might originate from the partial k-space gap opening due to density wave instability.

Highlights: • Multiferroic Fe-doped BaTiO{sub 3} nanorods. • Sol–gel. • Magnetoelectric coefficient. • Transmission electron microscopy. • Cole–Cole plots. - Abstract: Multiferroic BaFe{sub 0.01}Ti{sub 0.99}O{sub 3} (BFT1) and BaFe{sub 0.015}Ti{sub 0.985}O{sub 3} (BFT15) nanorods were prepared by a sol–gel synthesis and annealed at 700 °C/2 h. The tetragonal phase and nano dimensions of BFT samples are identified by X-ray diffraction and transmission electron microscopy. The enhancement in ferroelectricity depends upon low porosity, tetragonal phase, space charge field, larger surface area and oriented growth. The ferromagnetism depends upon partially filled inner shells, surface spins and oxygen vacancies. The magnetoelectric coefficient ismore »« less

Hydrostatic pressure effect on photoluminescence from a GaN{sub 0.015}As{sub 0.985}/GaAs quantum well

Journal Article Tsang, M S ; Wang, J N ; Ge, W K ; ... - Applied Physics Letters

Photoluminescence from a GaN{sub 0.015}As{sub 0.985}/GaAs quantum well has been measured at 15 K under hydrostatic pressure up to 9 GPa. Both the emissions from the GaNAs well and GaAs barrier are observed. The GaNAs-related peak shows a much weaker pressure dependence compared to that of the GaAs band gap. A group of new peaks appear in the spectra when the pressure is beyond 2.5 GPa, which is attributed to the emissions from the N isoelectronic traps in GaAs. The pressure dependence of the GaNAs-related peaks was calculated using the two-level model with the measured pressure coefficients of the GaAsmore »« less

Pressure and temperature dependence of the absorption edge of a thick Ga{sub 0.92}In{sub 0.08}As{sub 0.985}N{sub 0.015} layer

Journal Article Perlin, P ; Subramanya, S G ; Mars, D E ; ... - Applied Physics Letters

We have studied the pressure and temperature dependence of the absorption edge of a 4-{mu}m-thick layer of the alloy Ga{sub 0.92}In{sub 0.08}As{sub 0.985}N{sub 0.015}. We have measured the hydrostatic pressure coefficient of the energy gap of this alloy to be 51 meV/GPa, which is more than a factor two lower than that of GaAs (116 meV/GPa). This surprisingly large lowering of the pressure coefficient is attributed to the addition of only {approximately}1.5{percent} nitrogen. In addition, the temperature-induced shift of the edge is reduced by the presence of nitrogen. We can explain this reduction by the substantial decrease of the dilatationmore »« less

The correlated polar semimetal Ca₃Ru₂O₇ exhibits a rich phase diagram including two magnetic transitions (T_N = 56 K and T_C = 48 K) with the appearance of an insulating-like pseudogap (at T_C). In addition, there is a crossover back to metallic behavior at T* = 30 K, the origin of which is still under debate. We utilized ultrafast optical-pump optical-probe spectroscopy to investigate quasiparticle dynamics as a function of temperature in this enigmatic quantum material. We identify two dynamical processes, both of which are influenced by the onset of the pseudogap. This includes electron-phonon relaxation and, below T_C, the onsetmore »« less

Far-infrared investigation of the pseudogap in underdoped Pb{sub 2}Sr{sub 2}(Y/Ca)Cu{sub 3}O{sub 8}

Journal Article Reedyk, M ; Timusk, T ; Hsueh, Y ; ... - Physical Review, B: Condensed Matter

The optical conductivity of underdoped Pb{sub 2}Sr{sub 2}(Y/Ca)Cu{sub 3}O{sub 8} has been obtained from 40 to 700thinspcm{sup {minus}1} via Kramers-Kronig analysis of the c-axis-polarized reflectance measured at temperatures between 10 and 300 K. In the normal state at the lowest and highest frequencies where it is least obscured by a large phonon contribution, the background c-axis optical conductivity of underdoped Pb{sub 2}Sr{sub 2}(Y/Ca)Cu{sub 3}O{sub 8} is observed to decrease systematically as the temperature is lowered from 300 to near 150 K. Upon lowering the temperature further, the optical conductivity remains constant until the superconducting transition temperature of 65 K ismore »« less
