Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="pssa201329332-sec-0001" sec-type="section"> <p>We quantitatively interpret HAADF‐STEM images of SrRuO₃/Pr_0.7Ca_0.3MnO₃ (SRO/PCMO) superlattices. The images were taken in a probe‐corrected (<italic>c</italic>_s = 0) FEI microscope at 300 kV. The specimen thickness is estimated by comparing experimental and simulated <italic>Z</italic>‐contrast ratios. The intermixing at the interfaces is different for the growth of SRO on PCMO and that of PCMO on SRO. In addition, the thermal stability of SRO/PCMO superlattices is studied by HAADF‐STEM, based on a series of annealing experiments. <inline-graphic xlink:href="ark:/27927/pgg4sz0jmxm" content-type="pssa201329332-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> <p>Colored HAADF‐STEM image (<italic>V</italic> = 300 kV, <italic>c</italic>_s = 0 mm) of part of a SrRuO₃/Pr_0.7Ca_0.3MnO₃ epitaxial superlattice.</p> </sec> </abstract>
