Molecular spin-orbit excitations in the J_eff = 1/2 frustrated spinel GeCoO
K. Tomiyasu, M. K. Crawford, D. T. Adroja +9
We describe powder and single-crystal inelastic neutron scattering experiments on a spinel-type antiferromagnet GeCoO, represented by an effective total angular momentum J_…
Elastic Instabilities within Antiferromagnetically Ordered Phase in the Orbitally-Frustrated Spinel GeCoO
Tadataka Watanabe, Shigeo Hara, Shin-Ichi Ikeda +1
Ultrasound velocity measurements of the orbitally-frustrated GeCoO reveal unusual elastic instabilities due to the phonon-spin coupling within the antiferromagnetic phase.…
Spin-orbit coupling inactivity of Co ion in geometrically frustrated magnet GeCoO
Keisuke Tomiyasu, Ayaka Tominaga, Shigeo Hara +5
We report single-crystal neutron diffraction studies on a spinel antiferromagnet GeCoO, which exhibits magnetic order with a trigonal propagation vector and tetragonal latt…
Jahn-Teller Inactivity and Magnetic Frustration in GeCoO Probed by Ultrasound Velocity Measurements
Tadataka Watanabe, Shigeo Hara, Shin-Ichi Ikeda
Ultrasound velocity measurements of cubic spinel GeCoO in single crystal were performed for the investigation of shear and compression moduli. The shear moduli in the param…
Spin-charge-lattice coupling near the metal-insulator transition in Ca3Ru2O7
C. S. Nelson, H. Mo, B. Bohnenbuck +4
We report x-ray scattering studies of the c-axis lattice parameter in Ca3Ru2O7 as a function of temperature and magnetic field. These structural studies complement published transp…
Electronic structures of layered perovskite Sr2MO4 (M=Ru, Rh, and Ir)
S. J. Moon, M. W. Kim, K. W. Kim +11
We investigated the electronic structures of the two-dimensional layered perovskite Sr\textit{M}O (\textit{M}=4\textit{d} Ru, 4\textit{d} Rh, and 5\textit{d} Ir) using…
