Research Abstract |
Layered transition-metal oxides show interesting phenomena such as high-temperature superconducting. These materials have often have inhomogeneous charge distribution inside. By combing preparing effective sample preparation environment and the high-intensity neutron spectrometers newly being installed at J-PARC, we tried to reveal microscopic mechanisms of these phenomena by exploring the anomalies in magnetic a lattice dynamics. At this moment, we have found interesting behavior in magnons in Ni, Co and other related systems, which should be investigated continuously.
