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.
