“…Whereas ME effects refer to electrically induced magnetization, we report here on a pronounced stress-induced magnetization known as the piezomagnetic effect [8]. The coexistence of the ME effect and piezomagnetism and the potential to observe their coupling via the piezomagnetoelectric effect [9] make such films particularly attractive. Piezoelectrically controlled piezomagnetism for instance provides an alternative route towards the realization of various spintronic applications.…”

“…Finally, the magnetic point group symmetry of Cr 2 O 3 allows for the piezomagnetoelectric effect. The high inherent stress, a significant piezomagnetic moment and the possibility to realize high electric fields makes Cr 2 O 3 thin films ideal candidates for the challenging quest of the symmetry allowed but hitherto undiscovered piezomagnetoelectric effect [9].…”

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.

“…Nowadays the term multiferroic has been generalized to include materials having antiferroic orders [2,4,5]. One remarkable feature of multiferroics is that their magnetoelectric tensors are determined by the relation among their respective domain states, thus reflecting on the macroscopic properties [6,7]. Regarding the coupling among the order parameters, and consequently the coupling among the domain states, it has been proposed that in single-phase multiferroic systems the magnetoelectric coupling may arise directly between either the electrical and magnetic order parameters or indirectly via lattice strain [2,8].…”

In this work, electrical permittivity measurements in lead iron niobate ceramics (PFN) were performed in the frequency and temperature range from 10 kHz to 1.2 GHz and from 15 K to 450 K, respectively. The microwave dielectric results revealed unambiguously the magnetoelectric effect in the PFN and demonstrated that the nature of such coupling arises indirectly via ferroelastic contribution rather than a direct coupling between electrical and magnetic order parameters. Moreover, it was also verified that such coupling can be enhanced or suppressed depending on the relative orientation between the probing electric field and the macroscopic polarization.
