Structural properties and superconductivity of SrFe2As2-xPx and CaFe2As2-yPy
H. L. Shi, H. X. Yang, H. F. Tian +5
The SrFe2As2-xPx and CaFe2As2-yPy materials were prepared by a solid state reaction method. X-ray diffraction measurements indicate the single-phase samples can be successfully obt…

Structural features and tetragonal-orthorhombic phase transition in SrFe2As2 and CaFe2As2
C. Ma, H. X. Yang, H. F. Tian +7
The structural properties of the SrFe2As2 and CaFe2As2 compounds have been extensively analyzed by transmission electron microscopy (TEM) from room temperature down to 20K. The exp…
