Kinkless electronic junction along one dimensional electronic channel
Qirong Yao, Jae Whan Park, Choongjae Won +2
Here we report the formation of type-A and type-B electronic junctions without any structural discontinuity along a well-defined 1-nm-wide one-dimensional electronic channel within…
Hidden Antipolar Order Parameter and Entangled Neel-Type Charged Domain Walls in Hybrid Improper Ferroelectrics
M. H. Lee, C. -P. Chang, F. -T. Huang +5
Hybrid improper ferroelectricity (HIF) denotes a new class of polar instability by the mixture of two octahedral-distortion modes and can feature the coexistence of abundant head-t…
Magnetic excitations of the Cu quantum spin chain in SrCuPtO
J. C. Leiner, Joosung Oh, A. I. Kolesnikov +10
We report the magnetic excitation spectrum as measured by inelastic neutron scattering for a polycrystalline sample of SrCuPtO. Modeling the data by the 2+4 spinon contribu…
Spin glass behavior in frustrated quantum spin system CuAl2O4 with a possible orbital liquid state
R. Nirmala, Kwang-Hyun Jang, Hasung Sim +10
CuAl2O4 is a normal spinel oxide having quantum spin, S=1/2 for Cu2+. It is a rather unique feature that the Cu2+ ions of CuAl2O4 sit at a tetrahedral position, not like the usual…
Unfolding of vortices into topological stripes in a multiferroic material
Xueyun Wang, Maxim Mostovoy, Myung-Geun Han +4
Multiferroic hexagonal RMnO3 (R=rare earths) crystals exhibit dense networks of vortex lines at which six domain walls merge. While the domain walls can be readily moved with an ap…
Magnetic nano-fluctuations in a frustrated magnet
Krunoslav Prsa, Mark Laver, Martin Mansson +18
Frustrated systems exhibit remarkable properties due to the high degeneracy of their ground states. Stabilised by competing interactions, a rich diversity of typically nanometre-si…
