Elementary magnons and interacting multi-magnon quasiparticles in the effective spin- $\frac{1}{2}$ kagome-staircase magnet Co $_{3}$ V $_{2}$ O $_{8}$

Yuan Xiao, Jiajun Mo, Zhenmeng Jiang +6

The excitation spectrum of an anisotropic magnet provides a direct link between its microscopic Hamiltonian and interaction-driven quasiparticles. Here we use high-resolution time-…

Strongly frustrated 2D magnetism in a 3D hexagonal perovskite

Bocheng Yu, Otkur Omar, Songtai Lv +12

Exotic quantum phenomena are often found to occur in spin systems that exhibit low-dimensional magnetism. By combining nuclear magnetic resonance, neutron scattering, and muon-spin…

Dipolar and quadrupolar correlations in the $5 d^{2}$ Re-based double perovskites Ba $_{2}$ YReO $_{6}$ and Ba $_{2}$ ScReO $_{6}$

Otkur Omar, Yang Zhang, Qiang Zhang +8

Double perovskites containing heavy transition metal ions are an important family of compounds for the study of the interplay between electron correlation and spin-orbit coupling.…
