Ferroelectrics are attractive candidate materials for environmentally friendly solid state
refrigeration free of greenhouse gases. Their thermal response upon variations of external …

Relaxor ferroelectrics are complex oxide materials which are rather unique to study the
effects of compositional disorder on phase transitions. Here, we study the effects of …

Superconductivity has been observed in doped SrTiO $ _3 $ at charge-carrier densities
below 10$^{18} $ cm $^{-3} $, where the density of states at the Fermi level of the itinerant …

The fascinating dielectric property of relaxor ferroelectrics is investigated on the basis of
phase-transition dynamics within the mean-field theory. With a power-law distribution of the …

Investigations on Gd-substituted lead magnesium niobate (Pb 1-x Gd x Mg (1+ x)/3 Nb (2-
