Experimental and theoretical study of the influence of disorder on diffuse first-order phase transitions: NaNbO3: Gd and KTaO3: Li as examples
M. S. Prosandeeva, S. I. Rayevskaya, S. A. Prosandeev +2
We consider consequences of local disorder in systems experiencing first order phase transitions. Such systems can be of rather different nature. For example, manganates showing gi…

Dielectric Response in Microscopically Heterogeneous Dielectrics: Example of KTaO_3:Nb
S. Prosandeev, V. Trepakov, S. Kapphan +1
New experimental data on solid solutions of quantum paraelectrics with KTaO_3:Nb as an example are considered within a framework of a quantum theory of ferroelectric phase transiti…
