Tunable spin-valley coupling in layered polar Dirac metals
Masaki Kondo, Masayuki Ochi, Tatsuhiro Kojima +9
In non-centrosymmetric metals, spin-orbit coupling (SOC) induces momentum-dependent spin polarization at the Fermi surfaces. This is exemplified by the valley-contrasting spin pola…
Polar State induced by Block-type Lattice Distortions in BaFe2Se3 with Quasi-One-Dimensional Ladder Structure
Takuya Aoyama, Satoshi Imaizumi, Takuya Togashi +6
Temperature dependent crystal structures of the quasi-one-dimensional ladder material BaFe2Se3 are examined. Combining the optical second harmonic generation (SHG) experiments and…
Tuning the Ultrafast Spin Dynamics in Carrier-Density-Controlled Ferromagnets
Masakazu Matsubara, Alexander Schroer, Andreas Schmehl +7
Ultrafast strengthening or quenching of the ferromagnetic order of semiconducting Eu1-xGdxO was achieved by resonant photoexcitation. The modification of the magnetic order is esta…
Giant third-order magneto-optical rotation in ferromagnetic EuO
Masakazu Matsubara, Andreas Schmehl, Jochen Mannhart +2
A magnetization-induced rotation in the third-order nonlinear optical response is observed in out-of-plane-magnetized epitaxial EuO films. We discuss the relation of this nonlinear…
Ultrafast Photoinduced Formation of Metallic State in a Perovskite-type Manganite with Short Range Charge and Orbital Order
Yoichi Okimoto, Hiroyuki Matsuzaki, Yasuhide Tomioka +5
Femtosecond reflection spectroscopy was performed on a perovskite-type manganite, Gd0.55Sr0.45MnO3, with the short-range charge and orbital order (CO/OO). Immediately after the pho…
