“…By producing dielectric polarization with a mechanical strain and, conversely, a mechanical response with an applied electric eld, they have found applications in sensors, 1 energy harvesting, 2,3 actuators, 4 oscillators, 5,6 and many other elds. Most recent studies have focused on inorganic piezoelectric materials, such as AlN, 7 ZnO, 8 LiNbO 3 , 9 and lead zirconate titanate (PZT).…”

The piezoelectric and elastic properties of a molecular piezoelectric meta-nitroaniline (mNA) in its singlecrystal form were investigated in the framework of first-principles density functional perturbation theory (DFPT). Results support the recent experimental findings those despite being soft and flexible, mNA's piezoelectric coefficients are an order of magnitude greater than that of ZnO and LiNbO 3 . A molecularlevel insight into the piezoelectric properties of mNA is provided. These results are helpful not only for better understanding mNA, but also for developing new piezoelectric materials.

“…Conceptually, connectivity is a major factor affecting the modeling grounds for these composites [40]. Bilayer systems (2-2-connectivity, see Figures 2 and 21) of single crystal piezoelectric substrates and strongly magnetostrictive top layers furnish the best known sensors [8,[41][42][43][44][45][46]. If a metal is chosen for the magnetostrictive material, it can concurrently serve as electrode.…”

“…One among many examples for such films is a cobalt iron oxide and barium titanate heterostructure of 2-2-connectivity synthesized using pulsed laser deposition (PLD) [46]. Their films yielded an out of plane direct magnetoelectric voltage coefficient (longitudinal, L) of 104 mV/(cm·Oe).…”

Measuring the magnetoelectric effect across scales

Magnetoelectric coupling is the material based coupling between electric and magnetic fields without recurrence to electrodynamics. It can arise in intrinsic multiferroics as well as in composites. Intrinsic multiferroics rely on atomistic coupling mechanisms, or coupled crystallographic order parameters, and even more complex mechanisms. They typically require operating temperatures much below T = 0°C in order to exhibit their coupling effects. Room temperature applications are thus excluded. Consequently, composites have been designed to circumvent this limitation. They rely on field coupling between magnetostrictive and piezoelectric materials or in more advanced scenarios on quantum coupling in between both phases.This overview will describe experimental techniques and their particular limitations in accessing these coupling phenomena at different scales. Strain coupling is the dominant coupling mechanism at the macroscale as well as down to the micrometer. At the nanoscale more subtle effects can arise and some care has to be taken when investigating local coupling at interfaces using scanning probe techniques, e. g. due to semiconductor effects, field screening, or gradient and surface effects. At the smallest length scale atomic or molecular coupling can be tested using X‐ray dichroism or probe atoms like 57Fe in Mössbauer spectroscopy. We display a selection of measuring techniques at the different scales and outline possible pitfalls for experimentalists as well as theoreticians when using material parameters extracted from such experimental work.

“…[1][2][3][4] However, single phase multiferroic materials have relatively weak magnetoelectric (ME) coupling at room temperature limiting their device applications. In sharp contrast, a large ME coupling at room temperature is achievable with strain mediated composite multiferroics.…”

In this paper, we study the sputter deposition and crystallization process to produce high quality Terfenol-D thin film (100 nm) with surface roughness below 1.5 nm. The Terfenol-D thin film was produced using DC magnetron sputtering technique with various sputtering parameters and two different crystallization methods, i.e. substrate heating and post-annealing. Several characterization techniques including WDS, XRD, TEM, AFM, SQUID and MOKE were used to determine the physical and magnetic properties of the Terfenol-D films. TEM studies reveal that the film deposited on the heated substrate has large grains grown along the film thickness producing undesirable surface roughness while the film crystallized by post-annealing method shows uniformly distributed small grains producing a smooth surface. The Terfenol-D film was also deposited onto (011) cut PMN-PT single crystal substrate. With the application of an electric field the film exhibited a 1553 Oe change in coercivity with an estimated saturation magnetostriction of λs = 910 x 10−6.
