Lattice dynamics and thermal transport in multiferroic CuCrO2

Title: Lattice dynamics and thermal transport in multiferroic ${CuCrO}_{2}$

Abstract

Inelastic neutron and x-ray scattering measurements of phonons and spin waves in CuCrO ₂ were performed over a wide range of temperature, and complemented with first-principles simulations. The phonon dispersions and density of states are well reproduced by our density functional cal- culations, and reveal a strong anisotropy of Cu vibrations, with large amplitudes of low-frequency in-plane motions. In addition, we find that spin fluctuations persist above 300 K, far above the N eel temperature for long-range antiferromagnetic order, TN. Modeling of the thermal conductivity, based on our phonon measurements and simulations, reveals a significant anisotropy and indicates that the spin fluctuations above TN constitute a strong source of phonon scattering.

Spin-reorientation transitions in the Cairo pentagonal magnet ${Bi}_{4} {Fe}_{5} O_{13} F$

Journal Article Tsirlin, Alexander A. ; Rousochatzakis, Ioannis ; Filimonov, Dmitry ; ... - Physical Review B

Here, we show that interlayer spins play a dual role in the Cairo pentagonal magnet Bi ₄Fe ₅O ₁₃F, on one hand mediating the three-dimensional magnetic order, and on the other driving spin-reorientation transitions both within and between the planes. The corresponding sequence of magnetic orders unraveled by neutron diffraction and Mössbauer spectroscopy features two orthogonal magnetic structures described by opposite local vector chiralities, and an intermediate, partly disordered phase with nearly collinear spins. A similar collinear phase has been predicted theoretically to be stabilized by quantum fluctuations, but Bi ₄Fe ₅O ₁₃F is very far from the relevant parametermore »« less

Journal Article Pratt, Daniel K. ; Lynn, Jeffrey W. ; Mais, James ; ... - Physical Review. B, Condensed Matter and Materials Physics

The magnetic order, spin dynamics, and crystal structure of the multiferroic Sr0.56Ba0.44MnO3 have been investigated using neutron and x-ray scattering. Ferroelectricity develops at T-C = 305 K with a polarization of 4.2 mu C/cm(2) associated with the displacements of the Mn ions, while the Mn4+ spins order below T-N approximate to 200 K into a simple G-type commensurate magnetic structure. Below TN the ferroelectric order decreases dramatically, demonstrating that the two order parameters are strongly coupled. The ground state spin dynamics is characterized by a spin gap of 4.6(5) meV and the magnon density of states peaking at 43 meV.more »« less

Coexistence of antiferromagnetic and ferromagnetic spin correlations in $Ca {({Fe}_{1 - x} {Co}_{x})}_{2} {As}_{2}$ revealed by ${}^{75}{As}$ nuclear magnetic resonance

Journal Article Cui, J. ; Wiecki, P. ; Ran, S. ; ... - Physical Review B

Recent nuclear magnetic resonance (NMR) measurements revealed the coexistence of stripe-type antiferromagnetic (AFM) and ferromagnetic (FM) spin correlations in both the hole- and electron-doped BaFe ₂ As ₂ families of iron-pnictide superconductors by a Korringa ratio analysis. Motivated by the NMR work, we investigate the possible existence of FM fluctuations in another iron-pnictide superconducting family, Ca ( Fe _{1 - x}Co _x ) ₂ As ₂ . We reanalyzed our previously reported data in terms of the Korringa ratio and found clear evidence for the coexistence of stripe-type AFM and FM spin correlations in the electron-doped CaFe ₂ Asmore »« less

Anomalous phonon behavior in superconducting ${CaKFe}_{4} {As}_{4}$ : An optical study

Journal Article Yang, Run ; Dai, Yaomin ; Xu, Bing ; ... - Physical Review B

Here, the temperature dependence of ab-plane optical conductivity of CaKFe ₄As ₄ has been measured below and above its superconducting transition temperature T _c≃35.5 K. In the normal state, analysis with the two-Drude model reveals a T-linear scattering rate for the coherent response, which suggests strong spin-fluctuation scattering. Below the superconducting transition, the optical conductivity below 120 cm ^–1 vanishes, indicating nodeless gap(s). The Mattis-Bardeen fitting in the superconducting state gives two gaps of Δ ₁ ≃ 9 meV and Δ ₂ ≃ 14 meV, in good agreement with recent angle-resolved photoemission spectroscopy (ARPES) results. In addition, around 255 cmmore »« less
