A Robust Cost‐Effective Spectrophotometric Method for Nb Determination in Refractory Nb‐doped Gadolinium Zirconate: Overcoming Matrix Dissolution Challenges

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT A simple, robust and cost‐effective analytical methodology was developed for the determination of niobium in highly refractory materials: Nb‐doped gadolinium zirconate (Gd2Zr2O7:Nb) and niobium pentoxide (Nb2O5). The challenge of digesting these matrices was successfully accomplished by establishing two independent dissolution procedures: (i ...

Weyl magnons in pyrochlore antiferromagnets with all-in-all-out orders

, 2017
We investigate novel topological magnon band crossings of pyrochlore antiferromagnets with all-in-all-out (AIAO) magnetic order. By general symmetry analysis and spin-wave theory, we show that pyrochlore materials with AIAO orders can host Weyl magnons ...
