Soft-mode behavior of electromagnons in multiferroic manganite
A. M. Shuvaev, J. Hemberger, D. Niermann +6
The behavior of the low-frequency electromagnon in multiferroic DyMnO3 has been investigated in external magnetic fields and in a magnetically ordered state. Significant softening…
Magnetic and magnetoelectric excitations in TbMnO
A. Pimenov, A. Shuvaev, A. Loidl +5
Magnetic and magnetoelectric excitations in the multiferroic TbMnO_3 have been investigated at terahertz frequencies. Using different experimental geometries we can clearly separat…
Phase transitions in multiferroic BiFeO3 crystals, thin-layers, and ceramics: Enduring potential for a single phase, room-temperature magnetoelectric 'holy grail'
A. M. Kadomtseva, Yu. F. Popov, A. P. Pyatakov +3
Magnetic phase transitions in multiferroic bismuth ferrite (BiFeO3) induced by magnetic field, epitaxial strain, and composition modification are considered. These transitions from…
Terahertz spectroscopy of electromagnons in Eu_{1-x}Y_xMnO_3
A. Pimenov, A. Loidl, A. A. Mukhin +3
Dielectric permittivity spectra of yttrium-doped EuMnO in the composition range 0 =< x =< 0.5 have been investigated in the terahertz frequency range. Magnetoelectric contribut…
Charge Localization due to RKKY Interaction in the Spin Glass AuFe
B. Gorshunov, A. S. Prokhorov, S. Kaiser +11
Measurements of electrodynamic response of of spin glass AuFe films in comparison with pure gold films are performed at frequencies from 0.3 THz (10 cm-1) up to 1000 THz (33000 cm-…
Coupling of phonons and electromagnons in GdMnO_3
A. Pimenov, T. Rudolf, F. Mayr +3
The infrared and Terahertz properties of GdMnO_3 have been investigated as function of temperature and magnetic field, with special emphasis on the phase boundary between the incom…
