Abrupt appearance of the domain pattern and fatigue of thin ferroelectric films
A. M. Bratkovsky, A. P. Levanyuk
We study the domain structure in ferroelectric thin films with a `passive' layer (material with damaged ferroelectric properties) at the interface between the film and electrodes w…

Colossal magnetooptical conductivity in doped manganites
A. S. Alexandrov, A. M. Bratkovsky
We show that the current carrier density collapse in doped manganites, which results from bipolaron formation in the paramagnetic phase, leads to a colossal change of the optical c…

Theory of optical conductivity in doped manganites
A. S. Alexandrov, A. M. Bratkovsky
The frequency and temperature dependence of the optical conductivity of ferromagnetic manganites is explained within the framework of the bipolaron theory. As these materials are c…
