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…

Measurement of low energy charge correlations in underdoped spin-glass La-based cuprates using impedance spectroscopy
G. R. Jelbert, T. Sasagawa, J. D. Fletcher +3
We report on the charge kinetics of La_2CuO_4 lightly doped with Li and Sr. Impedance spectroscopy measurements down to 25mK and from 20Hz to 500kHz reveal evidence for low energy…
