Reduced crystal symmetry as origin of the ferroelectric polarization within the incommensurate magnetic phase of TbMn2O5

N. Narayanan, P. J. Graham, P. Rovillain +9

The precise crystal symmetry and hence the emergence of the electric polarization still remains an open question in the multiferroic materials MnO ( = rare-earth, Bi,…

Decoupling lattice and magnetic instabilities in frustrated CuMnO

Keith V. Lawler, Dean Smith, Shaun R. Evans +8

The MnO delafossites (=Na, Cu), are model frustrated antiferromagnets, with triangular layers of Mn~spins. At low temperatures (=65 K), a $C2/m \rightarro…

Spin-chain correlations in the frustrated triangular lattice material CuMnO

Simon A. J. Kimber, Andrew Wildes, Hannu Mutka +2

The Ising triangular lattice remains the classic test-case for frustrated magnetism. Here we report neutron scattering measurements of short range magnetic order in CuMnO, whic…

A valence bond liquid on the honeycomb lattice

Simon A. J. Kimber, I. I. Mazin, Juan Shen +5

The honeycomb lattice material Li2RuO3 undergoes a dimerization of Ru4+ cations on cooling below 270C, where the magnetic susceptibility vanishes. We use density functional theory…

Structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx

Hemke Maeter, Jorge Enrique Hamann Borrero, Til Goltz +17

We have studied the structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx by a detailed analysis of muon spin relaxation experiments, synchrotron X-ray diffract…

Low-temperature ferroelectric phase and magnetoelectric coupling in the underdoped La_2CuO_(4+x)

Z. Viskadourakis, I. Radulov, A. P. Petrović +9

We report the discovery of a ferroelectric ground state below 4.5 K in highly underdoped La_2CuO_(4+x) accompanied by slow charge dynamics which develop below T~40 K. An anisotropi…
