Description:
Author(s): D. E. MacLaughlin, O. O. Bernal, Lei Shu, Jun Ishikawa, Yosuke Matsumoto, J.-J. Wen, M. Mourigal, C. Stock, G. Ehlers, C. L. Broholm, Yo Machida, Kenta Kimura, Satoru Nakatsuji, Yasuyuki Shimura, and Toshiro Sakakibara The authors study the stuffed metallic pyrochlore Pr 2 + x Ir 2 − x O 7 − δ through specific heat, elastic neutron scattering, and muon spin rotation ( μ SR) measurements. They consider the question of why the static local field (B l o c ) as measured in μ SR is so small. They weigh two possible theories, the fluctuating-moment picture and the suppressed-moment picture, and argue that the available evidence leans toward the former, while stating that regardless of picture, this pyrochlore is very close to a magnetic-nonmagnetic critical point.
