“…Different kinds of lateral structures are demonstrated in literature, however, the most revealing experiments were performed on stripe-like structures. Therefore, the main focus in this review will be on these quasi 2-dimensional patterns [33,36,38,41,46].…”

“…The initialization or modification of the pinning direction in exchange coupled AF/FM bilayers by IB in an external magnetic field opens up possibilities for a remanent lateral magnetic patterning with inplane magnetic patterns if IB is performed through transmission masks [8][9][10][11][12]. The ion bombardment induced magnetic patterning (IBMP) can be performed essentially without a change in the sample's surface topography due to the low sputtering rate of He and the low doses needed for magnetic modifications.…”

In the present paper we investigate whether the ion bombardment induced magnetic modifications in exchange biased bilayers are stable in time, whether the direction of the exchange bias can be set to any arbitrary (in-plane) direction by the ion bombardment and whether the exchange bias field can be changed in successive bombardment steps. These three fundamental characteristics are prerequisites for ion bombardment used for an efficient, practical, and stable magnetic patterning of exchange biased layer systems.

“…MFM has been demonstrated as a robust technique for direct observation of magnetic domain and even the internal fine structures of different domain walls [165][166][167] with nanometer to sub-micrometer resolution [168][169][170]. MFM basically has the capability of imaging any field gradient emanating from the surface, making it possible to map any kinds of magnetic structures.…”

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.
