    Electric control of straight stripe conductive mixed-phase nanostructures in La-doped BiFeO3

    This study examines the atomic force microscope (AFM) tip-based electrical formation of tens of microns long stripe (and ∼100 nm wide) inorganic one-dimensional nanostructures based on the morphotropic phase b...

    Electric-field-induced spin disorder-to-order transition near a multiferroic triple phase point

    The emergence of a triple phase point in a two-dimensional parameter space (such as pressure and temperature) can offer unforeseen opportunities for the coupling of two seemingly independent order parameters. ...
