Spectral origin of the colossal magnetodielectric effect in multiferroic DyMn2O5
A. B. Sushkov, Ch. Kant, M. Schiebl +8
The origin of the colossal magnetodielectric effect in DyMn2O5 [1] has been an outstanding question in multiferroics. Here, we report the activation of the electric dipole mode at…
Optical identification of hybrid magnetic and electric excitations in Dy3Fe5O12 garnet
P. D. Rogers, Y. J. Choi, E. Standard +10
Far-infrared spectra of magneto-dielectric Dy3Fe5O12 garnet were studied between 13 and 100 cm-1 and at low temperatures between 5 and 80 K. A combination of transmission, reflecti…
Magnetic excitations in the low-temperature ferroelectric phase of multiferroic YMn2O5 using inelastic neutron scattering
J. -H. Kim, M. A. van. der. Vegte, A. Scaramucci +6
We studied magnetic excitations in a low-temperature ferroelectric phase of the multiferroic YMn2O5 using inelastic neutron scattering (INS). We identify low-energy magnon modes an…
Coupling between magnon and ligand-field excitations in magnetoelectric Tb3Fe5O12 garnet
T. D. Kang, E. Standard, K. H. Ahn +7
The spectra of far-infrared transmission in Tb3Fe5O12 magnetoelectric single crystals have been studied in the range between 15 and 100 cm-1, in magnetic fields up to 10 T, and for…
Magnetic excitations and optical transitions in the multiferroic spin-1/2 system LiCuO
D. Hüvonen, U. Nagel, T. Rõõm +4
Magnetic excitations in cycloidal magnet LiCuO are explored using THz absorption spectroscopy in magnetic fields up to 12 T. Below the spin ordering temperature we observe…
The incommensurate magnetic structure of YMn2O5: a stringent test of the multiferroic mechanism
P. G. Radaelli, C. Vecchini, L. C. Chapon +3
We have determined the magnetic structure of the low-temperature incommensurate phase of multiferroic YMn2O5 using single-crystal neutron diffraction. By employing corepresentation…
