Memory effect in triglycine sulfate induced by a transverse electric field: specific heat measurement

TL;DR

This study demonstrates that triglycine sulfate exhibits a memory effect in its specific heat, influenced by a transverse electric field, which can remember the temperature at which the field was applied.

Contribution

It reveals a novel memory effect in TGS's specific heat induced by a transverse electric field, expanding understanding of ferroelectric material behavior.

Findings

Specific heat of TGS is affected by a transverse electric field.

TGS can remember the temperature of previous field application.

Memory effect persists after heating through phase transition.

Abstract

The influence of a transverse electric field in the specific heat of triglycine sulphate (TGS) has been studied. The specific heat of TGS has been measured heating the sample from ferroelectric to paraelectric phase after prolonged transverse electric field (i.e. perpendicular to the ferroelectric axis). It is shown that the specific heat of TGS can remember the temperature $T_s$ at which the transverse field was previously applied.
