Local structure and hybridization states in Ba0.9Ca0.1Ti1 xZrxO3 ceramic compou...
Mastelaro, Valmor Roberto; Favarim, Higor Rogerio; Mesquita, Alexandre; Michalowicz, A.; Moscovici, J.; Eiras, J. A.This paper reports on a multi-edge X-ray absorption analysis to elucidate how the substitution of Ti4+ by Zr4+ ions acts on the local order structure and on the O 2p hybridization states of Ba0.9Ca0.1Ti1_xZrxO3 (BCZT) lead-free ceramic compounds, inducing a ferroelectric evolution from a normal to a relaxor character. Ti, Ba, Zr and O X-ray absorption spectra were measured to probe the local and electronic stru...
