Quasiparticle Dynamics in Ba2DyRuO6

Published:Dec 31, 2025 10:53
1 min read
ArXiv

Analysis

This paper investigates the magnetic properties of the double perovskite Ba2DyRuO6, a material with 4d-4f interactions, using neutron scattering and machine learning. The study focuses on understanding the magnetic ground state and quasiparticle excitations, particularly the interplay between Ru and Dy ions. The findings are significant because they provide insights into the complex magnetic behavior of correlated systems and the role of exchange interactions and magnetic anisotropy in determining the material's properties. The use of both experimental techniques (neutron scattering, Raman spectroscopy) and theoretical modeling (SpinW, machine learning) provides a comprehensive understanding of the material's behavior.
