Neutron scattering evidence for two-dimensionally coupled spin-dimerized antiferromagnetic lattice in α-Cu2P2O7

B. Ghanta, K. S. Chikara, M. Ghanathe +3

The microscopic magnetic model of the low-dimensional quantum magnet alpha-Cu2P2O7 has remained controversial. We present a comprehensive study of its magnetic ground state and exc…

Sizable Ligand-Mediated Bond-Dependent Interactions in a Spin-1 Triangular Antiferromagnet NiI

Hao Xu, Weiqin Zhu, Shufan Cheng +11

The bond-dependent anisotropic Kitaev interactions are the key for the Kitaev model, which has attracted intense interest for its potential to host quantum-spin-liquid states and f…

Multistage development of short-range spin correlations and weak magnetic order in the two coupled trillium lattices of K2Fe2(MoO4)(PO4)2

J. Khatua, Sritharan Krishnamoorthi, Changhyun Koo +11

Trillium lattices, where magnetic ions form a chiral network of corner-sharing triangles, offer a three-dimensional magnetic framework that can host fragile classical spin-liquid s…

Observation of Switchable Chiral Magnons in an Altermagnet

Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8

Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…

Bulk magnetic properties of distorted square lattice compounds M'-LnTaO4 (Ln = Tb, Dy, Ho, Er)

Nicola D. Kelly, Ivan da Silva, Siân E. Dutton

We report bulk magnetic properties of the monoclinic lanthanide tantalates, M'-LnTaO4 (Ln = Tb, Dy, Ho, Er), where the magnetic Ln3+ ions are arranged on a distorted 2D square latt…

Collective Phonon Mixing and Eigenvector Transport Under Isotope Substitution

Jeff Armstrong, Hamish Cavaye, Pankaj Sharma +1

Isotopic substitution modifies nuclear masses without altering the electronic potential energy surface to first order and is therefore often interpreted as a simple rescaling of vi…
