Abstract Abrikosov vortices in type-II superconductors influence current flow, dissipation and coherence, thereby limiting superconducting quantum technologies. In mesoscopic circuit elements, the entry and pinning of a single vortex can shift resonant frequencies, redistribute flux and degrade device performance.

Building on the structural analysis and the observed reciprocity between ST-FMR and AO, several key parameters, ρ xx , Tint , θ SH (including Tint ), and Ith , are analyzed across all Pt 100–x Bi x alloys (see Figures 5 a–c, S9 and S10 ). The electrical resistivity ρ xx increases with Bi concentration, rising from 65 μΩ·cm for 0.0% Bi to 270, 288, and 301 μΩ·cm for 3.9%, 6.0%, and 8.7% Bi, respectively ( Figure 5 a).

Abstract Controlling edge states of topological magnon insulators is a promising route to stable spintronics devices. However, to experimentally ascertain the topology of magnon bands is a challenging task. Here we derive a fundamental relation between the light-matter coupling and the quantum geometry of magnon states.
