Dipole-glass concept and history-dependent phenomena in relaxors

TL;DR

This paper discusses how the dipole-glass transition concept explains the unique physical properties and history-dependent phenomena observed in relaxor materials, aligning with glass-state theory.

Contribution

It introduces a comprehensive dipole-glass framework that accounts for all known anomalous features of relaxors, providing a unified explanation.

Findings

The dipole-glass concept explains relaxor anomalies.

History-dependent properties arise from metastable states.

Phenomenological descriptions match experimental observations.

Abstract

The possibility to explain basic physical properties of relaxors within the concept of the dipole-glass transition is discussed. We argue that this concept provides the only consistent picture accounting of all known anomalous features of relaxors. The origin of their history-dependent properties can be naturally traced to the main paradigm of glass-state theory - the existence of numerous metastable states. Based on this paradigm phenomenological description of known history-dependent phenomena in relaxors agrees qualitatively with experiments.
