TL;DR
This paper discusses potential explanations for non-zero Landau damping at q=0 in ferromagnetic superconductors UGe2 and UCoGe, focusing on Fermi surface intersections across different bands.
Contribution
It proposes a novel explanation linking Fermi surface intersections to observed Landau damping in ferromagnetic superconductors.
Findings
Fermi sheet intersections may cause non-zero Landau damping at q=0
The explanation aligns with experimental measurements in UGe2 and UCoGe
Highlights the role of band structure in magnetic damping phenomena.
Abstract
We have presented the potential explanation of nonvanishing at q=0 Landau damping measured experimentally in ferromagnetic compounds UGe2 and UCoGe based on possible intersection of the Fermi sheets corresponding different bands.
