Bi-quadratic magnetoelectric coupling in underdoped La_2CuO_{4+x}
S. Mukherjee, B. M. Andersen, Z. Viskadourakis +2
The recent discovery of relaxor ferroelectricity and magnetoelectric effect in lightly doped cuprate material La_2CuO_{4+x} has provided a number of questions concerning its theore…
Theory of the magnetoeletric effect in a lightly doped high-Tc cuprate
S. Mukherjee, B. M. Andersen, Z. Viskadourakis +2
In a recent study Viskadourakis et al. discovered that extremely underdoped La_2CuO_(4+x) is a relaxor ferroelectric and a magnetoelectric material at low temperatures. It is furth…
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…
Evidence for filamentary superconductivity nucleated at antiphase domain walls in antiferromagnetic CaFeAs
H. Xiao, T. Hu, A. P. Dioguardi +10
Resistivity, magnetization and microscopic As nuclear magnetic resonance (NMR) measurements in the antiferromagnetically ordered state of the iron-based superconductor paren…
