Giant Magnetic Fluctuations at the Critical Endpoint in Insulating HoMnO3
Y. J. Choi, N. Lee, P. A. Sharma +5
Although abundant research has focused recently on the quantum criticality of itinerant magnets, critical phenomena of insulating magnets in the vicinity of critical endpoints (CEP…
Terahertz spectroscopy of spin waves in multiferroic BiFeO in high magnetic fields
U. Nagel, Randy S. Fishman, T. Katuwal +5
We have studied the magnetic field dependence of far-infrared active magnetic modes in a single ferroelectric domain \BFO/ crystal at low temperature. The modes soften close to the…
Lattice and spin excitations in multiferroic h-YbMnO3
J. Liu, C. Toulouse, P. Rovillain +6
Lattice and spin excitations have been studied by Raman scattering in hexagonal YbMnO3 single crystals. The temperature dependences of the phonon modes show that the E2 mode at 256…
Complex Spin Structures and Origin of the Magneto-Electric Coupling in YMn2O5
J. -H. Kim, S. -H. Lee, S. I. Park +12
By combining neutron four-circle diffraction and polarized neutron diffraction techniques we have determined the complex spin structures of a multiferroic, YMn2O5, that exhibits tw…
Non-resonant and Resonant X-ray Scattering Studies on Multiferroic TbMn2O5
J. Koo, C. Song, S. Ji +15
Comprehensive x-ray scattering studies, including resonant scattering at Mn L-edge, Tb L- and M-edges, were performed on single crystals of TbMn2O5. X-ray intensities were observed…
Structural Anomalies at the Magnetic and Ferroelectric Transitions in (R=Tb, Dy, Ho)
C. R. dela Cruz, F. Yen, B. Lorenz +6
Strong anomalies of the thermal expansion coefficients at the magnetic and ferroelectric transitions have been detected in multiferroic . Their correlation with anomalies…
