- Abstract
Gd‐doped Sr0.5Ba0.5Nb2O6 (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 +Pr = 1.36 μC cm−2 and −Pr = −5.73 μC cm−2 and coercive field of +Ec = 158.0 kV and −Ec = −30.8 kV are obtained.
