Enhanced anisotropic spin fluctuations below tetragonal-to-orthorhombic transition in LaFeAs(O_{1-x}F_x) probed by ^{75}As and ^{139}La NMR
Yusuke Nakai, Shunsaku Kitagawa, Tetsuya Iye +4
As and La NMR results of LaFeAs(OF) (=0, 0.025, and 0.04) were reported. Upon F-doping, the tetragonal-to-orthorhombic structural phase transition tem…
Metamagnetic Behavior and Kondo Breakdown in Heavy-Fermion CeFePO
S. Kitagawa, H. Ikeda, Y. Nakai +5
We report that nonmagnetic heavy-fermion (HF) iron oxypnictide CeFePO with two-dimensional XY-type anisotropy shows a metamagnetic behavior at the metamagnetic field H_M \simeq 4 T…
Two-Dimensional Spin Dynamics in the Itinerant Ferromagnet LaCoPO Revealed by Magnetization and P-NMR Measurements
Hitoshi Sugawara, Kenji Ishida, Yusuke Nakai +5
We have performed magnetization and P-NMR measurements on the itinerant ferromagnet LaCoPO (Curie temperature K) with a layered structure in order to…
Itinerant Ferromagnetism in layered crystals LaCoOX (X = P, As)
Hiroshi Yanagi, Ryuto Kawamura, Toshio Kamiya +5
The electronic and magnetic properties of cobalt-based layered oxypnictides, LaCoOX (X = P, As), are investigated. LaCoOP and LaCoOAs show metallic type conduction, and the Fermi e…
