1306.4020 (David Sherrington)

BZT: a soft pseudo-spin glass. Comment on "Finite-Temperature Properties
of Ba(Zr; Ti)O_3 Relaxors from First Principles"

David Sherrington
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 Ba(Zr_xTi_{1-x})O_3 can be understood easily by a simple mapping to a soft pseudo-spin glass.
