Photo-induced phase transition on black samarium monosulfide
Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro +14
To investigate the role of the excitons for the origin of the pressure-induced phase transition (BGT) from the black-colored insulator (BI) to the golden-yellow-colored metal (GM)…
Photocarrier Transport of Ferroelectric Photovoltaic Thin Films Detected by the Magnetic Dynamics of Adjacent Ferromagnetic Layers
Yujun Zhang, Ji Ma, Keisuke Ikeda +7
We have observed photocarrier transport behaviors in BiFeO/LaSrMnO~(BFO/LSMO) heterostructures by using time-resolved synchrotron x-ray magnetic circular dichro…
Significant Unconventional Anomalous Hall Effect in Heavy Metal/Antiferromagnetic Insulator Heterostructures
Yuhan Liang, Liang Wu, Minyi Dai +16
The anomalous Hall effect (AHE) is a quantum coherent transport phenomenon that conventionally vanishes at elevated temperatures because of thermal dephasing. Therefore, it is puzz…
Photo-induced Antiferromagnetic-ferromagnetic Transition and Electronic Structure Modulation in GdBaCoO Thin Film
Yujun Zhang, Tsukasa Katayama, Akira Chikamatsu +9
We investigate both the ferromagnetic (FM) and antiferromagnetic (AFM) ultrafast dynamics of a strongly correlated oxide system, GdBaCoO thin film, by time-resolved x-r…
From Anomalous to Normal: Temperature Dependence of the Band Gap in Two-Dimensional Black Phosphorus
Shenyang Huang, Fanjie Wang, Guowei Zhang +11
The temperature dependence of the band gap is crucial to a semiconductor. Bulk black phosphorus (BP) is known to exhibit an anomalous behavior. Through optical spectroscopy, here w…
Spin-orbital liquid in BaCuSbO stabilized by oxygen holes
Kou Takubo, Takashi Mizokawa, Huiyuan Man +7
Both the Jahn-Teller distortion of CuO octahedra and magnetic ordering are absent in hexagonal BaCuSbO suggesting a Cu 3 spin-orbital liquid state. Here,…
