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…
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…
Multiferroicity in Geometrically Frustrated α-MCr_2O_4 systems (M=Ca, Sr, Ba)
Li. Zhao, Tian-Wey Lan, Kuen-Jen Wang +8
We have successfully synthesized three quasi-2D geometrically frustrated magnetic compounds (α-MCr_2O_4, M=Ca, Sr, Ba) using the spark-plasma-sintering technique. All these members…
