Synthesis, structure and physical properties of the new layered oxyselenides Bi2LnO4Cu2Se2 (Ln = rare earth).

We have synthesized a new series of layered oxyselenides Bi2LnO4Cu2Se2 (Ln=Nd, Sm, Eu, Dy, Er, Yb). Their crystal structures and physical properties were studied through X-ray diffraction, electric...
