Ferroelectric and Magnetic Domains in LuFe2O4 Observed by Scanning Probe Microscopy
I. K. Yang, J. Kim, S. H. Lee +3
LuFe2O4 is a multiferroic system which exhibits ferroelectricity, charge order, and ferrimagnetic order simultaneously below ~230 K. The ferroelectric domains of LuFe2O4 are imaged…
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…
Measurements and ab initio Molecular Dynamics Simulations of the High Temperature Ferroelectric Transition in Hexagonal RMnO3
T. A. Tyson, T. Wu, H. Y. Chen +5
Measurements of the structure of hexagonal RMnO3 (R=rare earths (Ho) and Y) for temperatures significantly above the ferroelectric transition temperature (TFE) were conducted to de…
High Pressure Structural Stability of Multiferroic Hexagonal REMnO3
P. Gao, Z. Chen, T. A. Tyson +6
Structural changes in REMnO3 (RE= Y, Ho, Lu) under high pressure were examined by synchrotron x-ray diffraction methods at room temperature. Compression occurs more readily in the…
Giant Magnetoelectric Effect in a Multiferroic Material with a High Ferroelectric Transition Temperature
N. Hur, I. K. Jeong, M. F. Hundley +2
We present a unique example of giant magnetoelectric effect in a conventional multiferroic HoMnO3, where polarization is very large (~56 mC/m2) and the ferroelectric transition tem…
Magnetic inversion symmetry breaking and ferroelectricity in TbMnO3
M. Kenzelmann, A. B. Harris, S. Jonas +7
TbMnO3 is an orthorhombic insulator where incommensurate spin order for temperature T_N < 41K is accompanied by ferroelectric order for T < 28K. To understand this, we establish th…
