Complex magnetism and magnetic field-driven electrical polarization in CoTeO

M. Hudl, R. Mathieu, S. A. Ivanov +8

The magnetic and electrical properties of CoTeO single-crystals with corundum related structure reveal a magnetic-field induced polarization below 21 K. A sharp peak in the…

Electrons doped in cubic perovskite SrMnO3: isotropic metal versus chainlike ordering of Jahn-Teller polarons

H. Sakai, S. Ishiwata, D. Okuyama +5

Single crystals of electron-doped SrMnO3 with a cubic perovskite structure have been systematically investigated as the most canonical (orbital-degenerate) double-exchange system,…

Electromagnons in the multiferroic state of perovskite manganites with symmetric-exchange striction

Y. Takahashi, S. Ishiwata, S. Miyahara +5

We have investigated electrically-active magnetic excitations (electromagnons) in perovskite manganites with the -type (up-up-down-down) spin structure by terahertz spectroscopy…

Perovskite Manganites Hosting Versatile Multiferroic Phases with Symmetric and Antisymmetric Exchange Strictions

S. Ishiwata, Y. Kaneko, Y. Tokunaga +3

Complete magnetoelectric (ME) phase diagrams of orthorhombic MnO with and without magnetic moments on the ions have been established. Three kinds of multiferroic groun…

Anisotropic order parameter in Li-intercalated layered superconductor LiZrNCl

M. Hiraishi, R. Kadono, M. Miyazaki +6

In this study, it is shown that in a layered nitride superconductor, i.e., LixZrNCl (0.07<=x<=0.21), the superconducting order parameter is highly anisotropic in a sample with x=0.…
