To carry out a more accurate study of the weak reconstruction of the local atomic structure we employed a combination of two techniques: (i) analysis of the preedge fine structure, and (ii) analysis of the Fourier transform of the difference between χ (k) functions obtained at different temperatures. A detailed investigation of local atomic structure in the cubic phase for all the crystals is also performed. It is shown that neither the displacive nor the order-disorder model can describe correctly the changes of local atomic structure during phase transitions in PZ and PZT. A spherical model describing the local atomic structure of perovskite-type crystals suffering structural phase transitions is proposed.","lang":"eng"}],"doi":"10.1103/PhysRevB.73.134109","_id":"2144","month":"04","publisher":"American Physical Society","intvolume":"        73","issue":"13","author":[{"last_name":"Vedrinskiǐ","full_name":"Vedrinskiǐ, Rostislav V","first_name":"Rostislav"},{"last_name":"Nazarenko","full_name":"Nazarenko, Elena S","first_name":"Elena"},{"full_name":"Mikhail Lemeshko","first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"last_name":"Nassif","first_name":"Vivian","full_name":"Nassif, Vivian M"},{"full_name":"Proux, Olivier","first_name":"Olivier","last_name":"Proux"},{"full_name":"Novakovich, Alexander A","first_name":"Alexander","last_name":"Novakovich"},{"last_name":"Joly","first_name":"Yves","full_name":"Joly, Yves"}],"citation":{"mla":"Vedrinskiǐ, Rostislav, et al. “Temperature Dependent XAFS Studies of Local Atomic Structure of the Perovskite-Type Zirconates.” <i>Physical Review B - Condensed Matter and Materials Physics</i>, vol. 73, no. 13, American Physical Society, 2006, doi:<a href=\"https://doi.org/10.1103/PhysRevB.73.134109\">10.1103/PhysRevB.73.134109</a>.","ista":"Vedrinskiǐ R, Nazarenko E, Lemeshko M, Nassif V, Proux O, Novakovich A, Joly Y. 2006.
