William Steinhardt, P. A. Maksimov, Sachith Dissanayake, Zhenzhong Shi, Nicholas Butch, David Graf, Andrey Podlesnyak, Yaohua Liu, Yang Zhao, Guangyong Xu, Jeffrey Lynn, Casey Marjerrison, A. L. Chernyshev, Sara Haravifard
Recently, Yb-based triangular lattice antiferromagnets have garnered significant interest as possible quantum spin liquid candidates. One example is YbMgGaO 4, which showed many promising spin liquid features, but also possesses a high degree of disorder

Magnetic Ordering and Structural Distortion in PrFeAsO Single Crystal Studied by Neutron and X-ray Scattering

M. G. Kim, William D. Ratcliff, D. M. Pajerowski, J.-W. Kim, J.-Q. Yan, Jeffrey W. Lynn, A. I. Goldman, A. Kreyssig
We report the magnetic ordering and structural distortion in PrFeAsO crystals, the basis compound for one of the oxypnictide superconductors, using high-resolution x-ray diffraction, neutron diffraction, and x-ray resonant magnetic scattering (XRMS). We

Isotropic Nature of the Metallic Kagome Ferromagnet Fe 3 Sn 2 at High Temperatures

Rebecca Dally, Daniel Phelan, Nicholas Bishop, Nirmal J. Ghimire, Jeffrey Lynn
Anisotropy and competing exchange interactions have emerged as two central ingredients needed for centrosymmetric materials to exhibit topological spin textures. Fe 3Sn 2 is thought to have these ingredients as well, as it has recently been discovered to

Charge Transfer Enhanced Magnetic Correlations in Type-II Multiferroic Co 3 TeO 6

Chi-Hung Lee, Erdembayalag Batsaikhan, Ma-Hsuan Ma, Wen-Hsien Li, Chin-Wei Wang, Chun-Min Wu, Hung-Duen Yang, Jeffrey W. Lynn, Helmuth Berger
Magnetic structure of the Co ions in monoclinic Co 3TeOd6^ in the antiferroelectric state at 16 K has been determined by neutron powder together with single crystal diffractions. The indices of the magnetic reflections that appear at the incommensurate

Field-Tuned Magnetic Structure and Phase Diagram of the Honeycomb Magnet YbCl 3

March 1, 2021

Yiqing Hao, Hongliang Wo, Yimeng Gu, Xiaowen Zhang, YiQing Gu, ShiYi Zheng, Yang Zhao, Guangyong Xu, Jeffrey W. Lynn, Naoki Murai, Wenbin Wang, Jun Zhao
We report thermodynamic and neutron diffraction measurements on the magnetic ordering properties of the honeycomb lattice magnet YbCl 3. We find YbCl 3 exhibits a Neel type long-range magnetic order at the wavevector (0,0,0) below T N = 600 mK. This

Evolution of the Magnetic Properties in the Antiferromagnet Ce 2 RhIn 8 Simultaneously Doped with Cd and Ir

D. S. Christovam, G. S. Freitas, M. M. Piva, J. C. Souza, M. O. Malcolms, O. L. Canton, Juscelino Leao, William D. Ratcliff, Jeffrey W. Lynn, C. Adriano, P. G. Pagliuso
We report the evolution of the magnetic properties of Ce 2Rh 1−xIr xIn 8−yCd y single crystals. In particular, for Ce 2Rh 0.5Ir 0.5In 8 (T N = 2.0 K) and Ce 2Rh 0.5Ir 0.5In 7.79Cd 0.21 (T N = 4.2 K), we have solved the magnetic structure of these compounds
