Incommensurate antiferromagnetic order in the manifoldly-frustrated SrTbO with transition temperature up to 4.28 K
Hai-Feng Li, Cong Zhang, Anatoliy Senyshyn +9
The Nel temperature of the new frustrated family of Sr\emph{RE}O (\emph{RE} = rare earth) compounds is yet limited to 0.9 K, which more or less hamper…
Distinct itinerant spin-density waves and local-moment antiferromagnetism in an intermetallic ErPdSi single crystal
Hai-Feng Li, Chongde Cao, Andrew Wildes +8
Identifying the nature of magnetism, itinerant or localized, remains a major challenge in condensed-matter science. Purely localized moments appear only in magnetic insulators, whe…
Nonmagnetic ordering state of single-crystal SrTmO: A polarized and unpolarized neutron-scattering study
Haifeng Li, Binyang Hou, Andrew Wildes +6
Our single-crystal polarized neutron scattering at 65 mK and powder unpolarized neutron diffraction at 0.5 K show no evidence for a long-range magnetic order and even detect no sig…
Possible magnetic-polaron-switched positive and negative magnetoresistance in the GdSi single crystal
Hai-Feng Li, Yinguo Xiao, Berthold Schmitz +5
Magnetoresistance (MR) has attracted tremendous attention for possible technological applications. Understanding the role of magnetism in manipulating MR may in turn steer the sear…
Flat band-engineered spin-density wave and the emergent multi- magnetic state in the topological kagome metal MnSn
Xiao Wang, Fengfeng Zhu, Xiuxian Yang +16
Magnetic kagome metals, in which topologically non-trivial band structures and electronic correlation are intertwined, have recently emerged as an exciting platform to explore exot…
Asymmetric rotations and dimerization driven by normal to modulated phase transition in 4-biphenylcarboxy coupled L-phenylalaninate
Somnath Dey, Supriya Sasmal, Saikat Mondal +7
Amongst the derivatives of 4-biphenylcarboxylic acid and amino acid esters, the crystal structure of 4-biphenylcarboxy-(L)-phenylalaninate is unusual owing to its monoclinic symmet…
Origin of forbidden reflections in multiferroic BaCoGeO by neutron diffraction: Symmetry lowering or Renninger effect?
Andrew Sazonov, Martin Meven, Georg Roth +4
For a symmetry consistent theoretical description of the multiferroic phase of BaCoGeO a precise knowledge of its crystal structure is a prerequisite. In our previous s…
Magnetization, crystal structure and anisotropic thermal expansion of single-crystal SrEr2O4
Hai-Feng Li, Andrew Wildes, Binyang Hou +5
The magnetization, crystal structure, and thermal expansion of a nearly stoichiometric SrErO single crystal have been studied by PPMS measuremen…
