Quantum-classical correspondence for spins at finite temperatures: theory and applications
A. El Mendili, M. E. Zhitomirsky
We derive a rigorous quantum-to-classical mapping for interacting spin systems at finite temperatures. Specifically, the large- asymptotic form of the partition function is give…
Strong and selective magnon-phonon coupling in van der Waals antiferromagnet CoPS
Dipankar Jana, Diana Vaclavkova, Rajesh Kumar Ulaganathan +6
The Raman scattering response of the biaxial antiferromagnet CoPS has been investigated as a function of both magnetic field and temperature. The peaks observed in the low-freq…
Longitudinal magnons in large- easy-axis magnets
A. El Mendili, T. Ziman, M. E. Zhitomirsky
Longitudinal magnons are a distinct type of multipolar excitations in magnetic materials with large spins and strong easy-axis anisotropy. These excitations have angular m…
Fully-frustrated octahedral antiferromagnets: emergent complexity in external field
A. S. Gubina, T. Ziman, M. E. Zhitomirsky
Octahedral antiferromagnets are distinguished by crystal lattices composed of octahedra of magnetic ions. In the fully frustrated case, the Heisenberg Hamiltonian can be represente…
Defect-induced spin textures in magnetic solids
M. E. Zhitomirsky, Vijay B. Shenoy, Roderich Moessner
Vacancy defects in isotropic noncollinear antiferromagnets produce long-range spin textures. By developing a "magnetic elasticity theory", we demonstrate that a vacancy-induced rea…
Tuning THz magnons in a mixed van-der-Waals antiferromagnet
F. Le Mardele, I. Mohelsky, D. Jana +9
Alloying stands out as a pivotal technological method employed across various compounds, be they metallic, magnetic, or semiconducting, serving to fine-tune their properties to mee…
