Hideya Onodera,Koji Kaneko,Takahiro Onimaru,Kenji Ohoyama,Yasuo Yamaguchi,Hisao Kobayashi,Yuichi Nemoto,Terutaka Goto +7 more
TL;DR: In this article, the second-order approximation of crystalline electric field (CEF) interaction has been used to analyze the magnetic properties of RB2C2 and PrB 2C2 compounds.
Versatility of advanced KINKEN triple-axis neutron spectrometer, AKANE
TL;DR: AKANE as mentioned in this paper is a thermal-neutron triple-axis spectrometer, which has been upgraded recently from the former double-axis neutron diffractometer, and the incident neutron energy is fixed to 20meV, which is intermediate between typical PG-filtered energies of 14.7 and 30.5.
Non-Fermi-Liquid Behavior on an Iron-Based Itinerant Electron Magnet Fe3Mo3N
Takeshi Waki,S. Terazawa,Yoshikazu Tabata,Fumiyasu Oba,Chishiro Michioka,Kazuyoshi Yoshimura,Shugo Ikeda,Hisao Kobayashi,Kenji Ohoyama,Hiroyuki Nakamura +9 more
TL;DR: In this paper, magnetic, calorimetric, and transport properties of an iron-based itinerant electron magnet Fe 3 Mo 3 N were reported, and the absence of magnetic long range order was confirmed by 57 Fe-Mossbauer and neutron diffraction measurements.
Resonance-Like Magnetic Excitations in Spinel Ferrimagnets FeCr2O4 and NiCr2O4 Observed by Neutron Scattering
TL;DR: In this paper, powder neutron scattering experiments on spinel ferrimagnets A Cr 2 O 4 with magnetic and Jahn-Teller A 2+ ions (A = Fe, Ni, Cu).
