Titanium doping of BiFeO3 ceramics and identification of minor phases by Raman spectroscopy

[EN] Titanium substitution can improve the multiferroic properties of bismuth ferrite materials, albeit the structural changes that this dopant produces in the perovskite structure of BiFeO are still not well understood. Due to its high sensitivity, Raman spectroscopy can be a useful tool for traili...
