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…
