BZT:a soft pseudo-spin glass

Abstract

In an attempt to understand the origin of relaxor ferroelectricity, it is shown that interesting behaviour of the onset of non-ergodicity and of precursor nanodomains found in first principles simulations of the relaxor alloy ${\mathrm{Ba}(\mathrm{Zr}}_{1-x}{\mathrm{Ti}}_x{)\mathrm{O}}_3$ can be understood easily by a simple mapping to a soft pseudo-spin glass.
