Orphan spins and bound in-gap states in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +11
CaFeO is an anisotropic antiferromagnet with two competing () and ($\uparrow \downarrow \uparrow \downar…
Solitary magnons in the antiferromagnet CaFeO
C. Stock, E. E. Rodriguez, N. Lee +10
CaFeO is a anisotropic antiferromagnet based upon zig-zag chains having two competing magnetic structures, denoted as the A ($\uparrow \uparrow \downarro…
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…
Evolution of the domain topology in a ferroelectric
S. C. Chae, Y. Horibe, D. Y. Jeong +4
Topological materials, including topological insulators, magnets with Skyrmions and ferroelectrics with topological vortices, have recently attracted phenomenal attention in the ma…
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…
Direct observation of the proliferation of ferroelectric loop domains and vortex-antivortex pairs
S. C. Chae, N. Lee, Y. Horibe +5
We discovered "stripe" patterns of trimerization-ferroelectric domains in hexagonal REMnO3 (RE=Ho, ---, Lu) crystals (grown below ferroelectric transition temperatures (Tc), reachi…
Helical spin-waves, magnetic order, and fluctuations in the langasite compound Ba3NbFe3Si2O14
C. Stock, L. C. Chapon, A. Schneidewind +6
We have investigated the spin fluctuations in the langasite compound Ba3NbFe3Si2O14 in both the ordered state and as a function of temperature. The low temperature magnetic structu…
