Title: Neutron inelastic scattering measurements of low-energy phonons in the multiferroic BiFeO₃

Abstract

In this study, we present neutron inelastic scattering measurements of the low-energy phonons in single crystal BiFeO₃. The dispersions of the three acoustic phonon modes (LA along [100], TA₁ along [010], and TA₂ along [110]) and two low-energy optic phonon modes (LO and TO₁) have been mapped out between 300 and 700 K. Elastic constants are extracted from the phonon measurements. The energy linewidths of both TA phonons at the zone boundary clearly broaden when the system is warmed toward the magnetic ordering temperature T_N=640 K. In conclusion, this suggests that the magnetic order and low-energy lattice dynamics in this multiferroic material are coupled.

Spin-phonon interactions of multiferroic Bi{sub 4}Ti{sub 3}O{sub 12}-BiFeO{sub 3} ceramics: Low-temperature Raman scattering and infrared reflectance spectra investigations

Journal Article Jiang, P. P. ; Zhang, X. L. ; Chang, P. ; ... - Journal of Applied Physics

Optical phonons of multiferroic Bi{sub 4}Ti{sub 3}O{sub 12}-BiFeO{sub 3} ceramic have been investigated by low temperature Raman scattering and infrared reflectance spectra. Anomalies at about 85 K can be observed from the temperature dependence of the Raman and infrared modes, which arise from spin-phonon interaction during antiferromagnetic to paramagnetic phase transition. It was found that the change of exchange interaction in magnetic phase transition can be induced by Fe-O-Fe octahedral tilting driven from the A-site atoms. Moreover, ferroelectricity-related displacement of Bismuth atoms suggests the coupling of magnetic and ferroelectric orders.

Neutron polarization analysis of the anisotropic spin wave excitations in multiferroic BiFeO₃

Conference Matsuda, Masaaki ; Dissanayake, Sachith E. ; Ito, T.

A multiferroic material BiFeO₃ shows a cycloidal spin structure below 640 K. Anisotropy of the magnetic excitations below 6 meV was previously studied using neutron polarization analysis (Zhang et al. 2022 Phys. Rev. B 105 144426). The magnetic excitations in and out of the cycloidal plane were separated and compared to those calculated based on the linear spin-wave theory. The overall feature of the observed excitations was found to be consistent with those calculated. Further polarized neutron study with extended energy range has been performed. The anisotropy of the magnetic excitations is present at least up to 15 meV. Themore »« less

Anisotropic spin-wave excitations in multiferroic BiFeO 3

Journal Article Zhang, Depei ; Dissanayake, Sachith ; Winn, Barry ; ... - Physical Review. B

Polarized inelastic neutron-scattering experiments have been performed to elucidate the anisotropic behavior of the low-energy spin-wave excitations in a multiferroic BiFeO₃, which shows a cycloidal spin structure below 640 K. Using neutron polarization analysis for single magnetic domain crystals, magnetic excitation modes in and out of the cycloidal plane below 6 meV were separated successfully. The magnetic excitation spectra were analyzed using linear spin-wave theory. The low-energy magnon density of states consist of several magnon modes, including the two anisotropic modes, Φ and Ψ modes, distributed in and out of the cycloidal plane, respectively, which were previously observed using opticalmore »« less

Spin state and spectroscopic modes of multiferroic BiFeO $_{3}$

Journal Article Fishman, Randy Scott ; Haraldsen, Jason T. ; Furukawa, Nobuo ; ... - Physical Review. B, Condensed Matter and Materials Physics

Spectroscopic modes provide the most sensitive probe of the very weak interactions responsible for the properties of the long-wavelength cycloid in the multiferroic phase of BiFeO₃ below T_N ≈ 640 K. Three of the four modes measured by terahertz (THz) and Raman spectroscopies were recently identified using a simple microscopic model. While a Dzyaloshinskii-Moriya (DM) interaction D along [-1, 2, -1] induces a cycloid with wave vector (2π/α) (0.5 + δ, 0.5, 0.5 - δ) (δ ≈ 0.0045), easy-axis anisotropy K along the [1, 1, 1] direction of the electric polarization P induces higher harmonics of the cycloid, which split themore »« less
