Abstract

Gd-doped Sr _0.5 Ba _0.5 Nb ₂ O ₆ (SBN50) thin films with Gd-doping concentration ranging from 1 to 4% are grown on Pt-coated MgO (100) substrates using pulsed laser deposition technique. X-ray diffraction studies show that the films are highly (001)-oriented and epitaxially grown on the substrates. Electrical measurements show that the Gd-SBN films possess good ferroelectric properties. Ramanent polarization of +P _r = 1.36 μC cm ⁻² and −P _r = −5.73 μC cm ⁻² and coercive field of +E _c = 158.0 kV and −E _c = −30.8 kV are obtained.
