We report multiferroic properties of Pb(Fe1/2Nb1/2)O3 (or PFN) epitaxial thin layers grown on (001), (110), and (111) SrTiO3 substrates with and without a SrRuO3 (SRO) buffer. Our findings are as follows: (i) the constraint stress on (001) substrates is more than ten times larger than those on (110) and (111); (ii) this large constraint stress induces higher piezoelectric constants, magnetic permeability and magnetization for (001) PFN compared with (110) and (111) layers; (iii) epitaxy distorts the structure of (001) PFN causing the films to be weakly ferromagnetic, whereas (110) films are antiferromagnetic; and (iv) a significant increase of the coercivity of (001) layers occurs due to clamping by a SRO buffer layer.

    La0.7Sr0.3MnO3 (LSMO) thin films with a thickness d of 10, 20, 60, and 100 nm were grown on 20-nm-thick SrTiO3-buffered (100) silicon substrates by a reactive molecular beam epitaxy. For all samples, x-ray diffraction (XRD) revealed an excellent epitaxy with in-plane cubic [100] and [010] axes...

    The phenomenon of training in exchange bias systems has no clear and unambiguous explanation. It is known that the training effect consists of an athermal and a thermal component where the latter derives from the well understood thermal instability in the bulk of the antiferromagnetic (AF)...

    Postgrowth annealing effects on a heteroepitaxial MnAs thin film grown on a GaAs(001) substrate have been investigated. The β-MnAs phase domains of an as-grown sample, observed as dark stripes in the surface topography at room temperature, disappear completely after postgrowth annealing. In...
