Phase co-existence and structured diffuse scattering seen by X-ray 3D mapping of reciprocal space for Cs0.8Fe1.6Se2
A. Bosak, V. Svitlyk, A. Krzton-Maziopa +6
AxFe2-ySe2 (A=K, Rb, Cs) superconductors may show a complex mixture of structural phases even in a single crystal form. A full sphere of the diffraction intensity has been collecte…
Iron vacancy superstructure and possible room temperature antiferromagnetic order in superconducting Cs_{y}Fe_{2-x}Se_2
V. Yu. Pomjakushin, D. V. Sheptyakov, E. V. Pomjakushina +5
Neutron and x-ray powder and single crystal synchrotron diffraction of CsyFe2-xSe2 show the presence of superstructure reflections with propagation vector k=[2/5, 1/5, 1] with resp…
A new model of correlated disorder in relaxor ferroelectrics
A. Bosak, D. Chernyshov, S. Vakhrushev +1
We propose a simple phenomenological picture to explain the unusual dielectric properties of the proto-typical ferroelectric relaxor lead magnesium niobate-titanate (PMN-PT). Our m…
