Photovoltaic effect by soft phonon excitation
Yoshihiro Okamura, Takahiro Morimoto, Naoki Ogawa +7
Photodetection is an indispensable function of optoelectronic devices in modern communication and sensing systems. Contrary to the near-infrared/visible regions, the fast and sensi…
Emergence of topological Hall effect in half-metallic manganite thin films by tuning perpendicular magnetic anisotropy
M. Nakamura, D. Morikawa, X. Z. Yu +4
Magnetic materials hosting topological spin textures like magnetic skyrmion exhibit nontrivial Hall effect, namely, topological Hall effect (THE). In this study, we demonstrate the…
The photoinduced transition in magnetoresistive manganites: a comprehensive view
V. Esposito, L. Rettig, E. Abreu +12
We use femtosecond x-ray diffraction to study the structural response of charge and orbitally ordered PrCaMnO thin films across a phase transition induced by 800 nm…
Nonlinear electron-phonon coupling in doped manganites
V. Esposito, R. Mankowsky, M. Fechner +9
We employ time-resolved resonant x-ray diffraction to study the melting of charge order and the associated insulator-metal transition in the doped manganite PrCaMnO…
Orbital Ordering Structures in (Nd,Pr)0.5Sr0.5MnO3 Manganite Thin Films on Perovskite (011) Substrates
Y. Wakabayashi, D. Bizen, Y. Kubo +6
Structural study of orbital-ordered manganite thin films has been conducted using synchrotron radiation, and a ground state electronic phase diagram is made. The lattice parameters…
Optical probe of electrostatic doping in an n-type Mott insulator
M. Nakamura, A. Sawa, H. Sato +3
Electrostatic doping into an -type Mott insulator SmCuO has been successfully achieved with use of the heterojunction with an -type band semiconductor Nb-doped Sr…
