Strongly spin-orbit coupled two-dimensional electron gas emerging near the surface of polar semiconductors
M. Sakano, M. S. Bahramy, A. Katayama +12
We investigate the two-dimensional (2D) highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X = I, Br, and…
Neutron Brillouin scattering with pulsed spallation neutron source - spin-wave excitations from ferromagnetic powder samples -
S. Itoh, Y. Endoh, T. Yokoo +4
Neutron Brillouin scattering (NBS) method was developed using a pulsed spallation neutron source, and the feasibility of NBS was demonstrated by observing ferromagnetic spin waves…
Glass-like recovery of antiferromagnetic spin ordering and dimensional crossover in a photo-excited manganite PrCaMnO
S. Y. Zhou, M. C. Langner, Y. Zhu +10
Electronic orderings of charges, orbitals and spins are observed in many strongly correlated electron materials, and revealing their dynamics is a critical step toward understandin…
Formation and rotation of skyrmion crystal in the chiral-lattice insulator Cu2OSeO3
S. Seki, J. -H. Kim, D. S. Inosov +4
Small angle neutron scattering experiments were performed on a bulk single crystal of chiral-lattice multiferroic insulator CuOSeO. In the absence of an external magnetic f…
Mott versus Slater-type metal-insulator transition in Mn-substituted Sr3Ru2O7
M. A. Hossain, B. Bohnenbuck, Y. D. Chuang +15
We present a temperature-dependent x-ray absorption (XAS) and resonant elastic x-ray scattering (REXS) study of the metal-insulator transition (MIT) in Sr3(Ru1-xMnx)2O7. The XAS re…
Magnetoelectric nature of skyrmions in a chiral magnetic insulator Cu2OSeO3
S. Seki, S. Ishiwata, Y. Tokura
Dielectric properties were investigated under various magnitudes and directions of magnetic field (H) for a chiral magnetic insulator Cu2OSeO3. We found that the skyrmion crystal i…
Imprinting magnetic information in manganites with X-rays
M. Garganourakis, V. Scagnoli, S. W. Huang +6
The effect of x-rays on an orbital and charge ordered epitaxial film of a PrCaMnO is presented. As the film is exposed to x-rays, the antiferromagnetic respon…
Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting
M. Sakano, J. Miyawaki, A. Chainani +12
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we in…
Observation of magnetic excitations of skyrmion crystal in a helimagnetic insulator
Y. Onose, Y. Okamura, S. Seki +2
The skyrmion is a topologically stable spin texture, in which the spin direction wraps a sphere. The topological nature gives rise to emergent electromagnetic phenomena such as top…
Spin-stretching modes in anisotropic magnets: spin-wave excitations in the multiferroic Ba2CoGe2O7
K. Penc, J. Romhányi, T. Rõõm +10
We studied spin excitations of the multiferroic Ba2CoGe2O7 in high magnetic fields up to 33 T. In the electron spin resonance and far infrared absorption spectra we found several s…
