Query: Magnetic Field Tunable Capacitive Dielectric:Ionic-liquid Sandwich
  Composites   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.
