Collapse of the Fe-vacancy order and successive phase transitions in superconducting KxFe2-ySe2 (0.7 \leg x \leg 0.8, 0.2 \leg y \leg 0.3)
J. Q. Li, Y. J. Song, H. X. Yang +6
The Fe-based superconducting KxFe2-ySe2 (0.6 {\leg} x {\leg} 1, 0.2{\leg} y {\leg} 0.4) compounds, unlike the well-known RFe2As2 (R = Ba, Sr, Ca) superconductors, contain complex s…
Phase transition, superstructure and physical properties of K2Fe4Se5
Y. J. Song, Z. Wang, Z. W. Wang +6
The structural features and physical properties of the antiferromagnetic K0.8Fe1.6Se2 (so called K2Fe4Se5 phase) have been studied in the temperature range from 300K up to 600K. Re…
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…
Off-axis electron holography and microstructure of Ba0.5Sr0.5TiO3 thin film grown on LaAlO3
H. F. Tian, H. C. Yu, X. H. Zhu +4
Epitaxial Ba0.5Sr0.5TiO3 thin films grown on the (001) LaAlO3 substrates with the ferroelectric transition of about 250K have been investigated by TEM and off-axis electron hologra…
