Structural and Superconducting Properties of K0.8Fe1.6+xSe2 single crystals
Abstract
We report structural and superconducting properties of K0.8Fe1.6+xSe2 single crystals. Superconducting properties were studied by using transport, specific heat and magnetization measurements, and compared with that of FeSe1-xTex. We found the c-axis resistive transition and specific heat behavior are distinctively different in these two classes of materials. Structural properties were studied via transmission electron microscopy and energy-dispersive X-ray spectroscopy. We found large scale structural and chemical disorder in the K0.8Fe1.6+xSe2 samples. The relationship between structural and superconducting properties in K0.8Fe1.6+xSe2 will be discussed.
