Relaxor Ferroelectrics and Related Cluster Glasses

What Can Spin Glass Theory and Analogies Tell Us About Ferroic Glasses?

“…The key ingredients to permit such glassy behaviour appear to be frustrated interactions and quenched disorder, as has often been expressed before. Probing these The simple analogies considered here suggest further conceptual transfers between different ferroic materials and further experimental investigations; for further discussion concerning characteristic experimental aspects of spin glasses see [97]; for a complemetary recent discussion of relaxors see [54].…”

“…Given that the B-site interactions are (quasi-)random, so are the effective fields. Let us concentrate now on the possible effects of including the random fields, which have been considered as driving forces for relaxor behaviour in PMN, particularly since the work of [52]; for more recent discussion see [53] [54].…”

“…This conceptualization was used in the context of itinerant spin glasses in the early 70's [76] and has become popular in considerations of relaxors; for a recent discussions see e.g. [53] [77] [78] [54].…”
