Highly C-Axis-Oriented Pb(Zr, Ti)O3 Films Prepared by Sputtering

Abstract
A newly developed tripole magnetron sputtering system, which has a third magnetic pole, has been applied to deposit PZT films in the atomic layer epitaxy mode. A set of experimental results revealed that the resultant films were highly c-axis orientated on (100) MgO substrates and that the deviation from stoichiometry in the films enhanced asymmetric properties of the P-E loop patterns.
