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…

The spin anisotropy of the magnetic excitations in the normal and superconducting states of optimally doped YBa2Cu3O6.9 studied by polarized neutron spectroscopy
N. S. Headings, S. M. Hayden, J. Kulda +2
We use inelastic neutron scattering with spin polarization analysis to study the magnetic excitations in the normal and superconducting states of YBa2Cu3O6.9. Polarization analysis…
