Fe-vacancy ordered Fe4Se5: The insulating parent phase of FeSe superconductor
Keng-Yu Yeh, Yan-Rai Chen, Tung-Sheng Lo +4
We have carried out a detailed study to investigate the existence of an insulating parent phase for FeSe superconductor. The insulating Fe4Se5 with specific Fe-vacancy order shows…
Possible Topological Phase Transition in Fe-Vacancy-Ordered -FeSe Nanowires
Keng-Yu Yeh, Tung-Sheng Lo, Chung-Chieh Chang +4
We studied the electrical transport on -FeSe single-crystal nanowires, exhibiting Fe-vacancy order and mixed valence of Fe. We observed a…
Role of the Extra-Fe in K2-xFe4+ySe5 superconductors
Chih-Han Wang, Chih-Chien Lee, Gwo-Tzong Huang +5
The exact superconducting phase of K2-xFe4+ySe5 has yet conclusively decided since its discovery due to its intrinsic multiphase in early material. In an attempt to resolve the mys…
Mn3TeO6 - A New Multiferroic Material with Two Magnetic Substructures
L. Zhao, Z. Hu, C. Y. Kuo +4
From magnetic susceptibility, dielectric permittivity, electric polarization and specific heat measurements, we discover spin-induced ferroelectricity and magnetoelectric coupling…
Disordered Fe vacancies and superconductivity in potassium-intercalated iron selenide (K2-xFe4+ySe5)
Chih-Han Wang, Ta-Kun Chen, Chung-Chieh Chang +5
The parent compound of an unconventional superconductor must contain unusual correlated electronic and magnetic properties of its own. In the high-Tc potassium intercalated FeSe, t…
Observation of pseudogap-like feature above Tc in LiFeAs and (Ba0.6K0.4)Fe2As2 by ultrafast optical measurement
Kung-Hsuan Lin, Kuan-Jen Wang, Chung-Chieh Chang +8
We utilize ultrafast optical measurement to study the quasiparticle relaxation in stoichiometric LiFeAs and nearly optimally doped (BaK)Fe2As2 crystals. According to our temperatur…
