Author(s)
Y. Chen, Sung Chang, Yang Zhao, Songxue Chi, William D. Ratcliff, B. G. Ueland, Ross Erwin
The new thermal triple-axis spectrometer at the NIST Center for Neutron Research (NCNR) is located at the BT-7 beam port. The 165 mm diameter reactor beam is equipped with a selection of Söller collimators, beam-limiters, and pyrolytic graphite (PG) filter

Antiferromagnetic Spin Excitations in Single Crystals of Nonsuperconducting Li 1-x FeAs

June 24, 2011

Meng Wang, X. C. Wang, D. L. Abernathy, L. W. Harriger, H. Q. Luo, Yang Zhao, Jeffrey W. Lynn, Q. Q. Liu, C. Q. Jin, Chen Fang, Jianping Hu, Pengcheng Dai
We use neutron scattering to determine spin excitations in single crystals of nonsuperconducting Li 1¿xFeAs throughout the Brillouin zone. Although angle resolved photoemission experiments and local density approximation calculations suggest poor Fermi
