Large magnetoelectric effect in ferroelectric/piezomagnetic heterostructures

Complex functional oxide heterostructures

This article presents a review of some salient aspects of a broad class of functional materials, namely complex oxides. These materials, exemplified by the rare earth manganites, superconducting cuprates and more recently multiferroics, are characterized by a complex crystal chemistry, that is central to competing/ cooperating spin, charge, orbital and lattice degrees of freedom. In addition to...

Ultrafast strain engineering in complex oxide heterostructures.

We report on ultrafast optical experiments in which femtosecond midinfrared radiation is used to excite the lattice of complex oxide heterostructures. By tuning the excitation energy to a vibrational mode of the substrate, a long-lived five-order-of-magnitude increase of the electrical conductivity of NdNiO(3) epitaxial thin films is observed as a structural distortion propagates across the int...
