    Flexoelectric polarizing and control of a ferromagnetic metal

    Electric polarization is well defined only in insulators not metals, and there is no general scheme to induce and control bulk polarity in metals. Here we circumvent this limitation by utilizing a pseudo-elect...

    Oxygen vacancy-induced topological nanodomains in ultrathin ferroelectric films

    Oxygen vacancy in oxide ferroelectrics can be strongly coupled to the polar order via local strain and electric fields, thus holding the capability of producing and stabilizing exotic polarization patterns. Ho...
