Metamagnetic Quantum Criticality Revealed by 17O-NMR in the Itinerant Metamagnet Sr3Ru2O7

Kentaro Kitagawa, Kenji Ishida, Robin S. Perry +3

We have investigated the spin dynamics in the bilayered perovskite Sr3Ru2O7 as a function of magnetic field and temperature using 17O-NMR. This system sits close to a metamagnetic…

Valence changes associated with the metal-insulator transition in Bi $_{1 - x}$ La $_{x}$ NiO $_{3}$

H. Wadati, M. Takizawa, T. T. Tran +9

Perovskite-type BiNiO $_{3}$ is an insulating antiferromagnet in which a charge disproportionation occurs at the Bi site. La substitution for Bi suppresses the charge disproportionati…

Orbital ordering and one-dimensional magnetic correlation in vanadium spinel oxides AV2O4 (A = Zn, Mg, or Cd)

Yukitoshi Motome, Hirokazu Tsunetsugu

We present our theoretical results on the mechanism of two transitions in vanadium spinel oxides $A$ V $_{2}$ O $_{4}$ ( $A$ =Zn, Mg, or Cd) in which magnetic V cations constitute a geometri…
