Magnetic Field Tunable Capacitive Dielectric:Ionic-liquid Sandwich Composites

TL;DR

This study demonstrates that the capacitance of GaFeO3-ionic liquid-GaFeO3 composites can be significantly tuned using external magnetic and electric fields, achieving up to 1.6-fold enhancement at specific conditions.

Contribution

The paper introduces a novel magnetic field tunable capacitive dielectric composite using ionic liquids and demonstrates its capacitance modulation capabilities.

Findings

Capacitance can be tuned up to 1.6 times at 957kHz with 4V and 0.02T magnetic field.

Capacitance enhancement is due to polarization coupling between dielectric and ionic liquid layers.

External magnetic and electric fields effectively modulate the composite's capacitance.

Abstract

We examined the tunability of the capacitance for GaFeO3-ionic liquid-GaFeO3 composite material by external magnetic and electric field. Up to 1.6 folds of capacitance tunability could be achieved at 957kHz with voltage 4v and magnetic field 0.02T applied. We show that the capacitance enhancement is due to the polarization coupling between dielectric layer and ionic liquid layer.
