Piezoelectric materials, which convert mechanical to electrical energy and vice versa, are typically characterized by the intimate coexistence of two phases across a morphotropic phase boundary. Electrically switching one other yields large electromechanical coupling coefficients. Driven global environmental concerns, there is currently strong push discover practical lead-free piezoelectrics for device engineering. Using combination epitaxial growth techniques in conjunction with theoretical...
We report the formation of a novel ferromagnetic state in antiferromagnet ${\mathrm{BiFeO}}_{3}$ at interface with ferromagnet ${\mathrm{La}}_{0.7}{\mathrm{Sr}}_{0.3}{\mathrm{MnO}}_{3}$. Using x-ray magnetic circular dichroism Mn and Fe ${L}_{2,3}$ edges, we discovered that development this spin structure is strongly associated onset significant exchange bias.

Investigations on the ferroelectric domains crystal structures with situ electric fields reveal that effect is related to combined action of 109° ferroelastic domain switching absence magnetocrystalline anisotropy Co(40)Fe(40)B(20).

The physical origin of this remarkable enhancement has been investigated by combination x-ray absorption spectroscopy, scanning transmission electron microscopy, and first principles calculations.

The electronic conductivities of ferroelectric domain walls have been extensively explored over the past decade for potential nanoelectronic applications. However, realization logic devices based on requires reliable and flexible control domain-wall configuration conduction path. Here, we demonstrate electric-field-controlled stable repeatable on-and-off switching conductive within topologically confined vertex domains naturally formed in self-assembled nano-islands.

Perovskite multiferroics have drawn significant attention in the development of next-generation multifunctional electronic devices. However, majority existing exhibit ferroelectric and ferromagnetic orderings only at low temperatures. Although interface engineering complex oxide thin films has triggered many exotic room-temperature functionalities, desired coupling charge, spin, orbital lattice degrees freedom often imposes stringent requirements on deposition conditions, layer thickness...

A central goal of electronics based on correlated materials or 'Mottronics' is the ability to switch between distinct collective states with a control voltage. Small changes in structure and charge density near transition can tip balance competing phases, leading dramatic electronic magnetic properties.

Abstract A controllable ferroelastic switching in ferroelectric/multiferroic oxides is highly desirable due to the non-volatile strain and possible coupling between lattice other order parameter heterostructures.
