We study magnetoelectric interactions in horizontal multiferroic
heterostructures that consist of a ferroelectric material (substrate or thin film) and
ferromagnet (thin film). We are particularly interested in the coupling between
domains in neighboring films with different ferroic order (coupling either
mediated by strain or polarization switching) and electric-field controlled
magnetism
In another project we study the tunability of ferromagnetic resonance in multiferroic
heterostructures.
Figure: Recent experimental result demonstrating the
imprinting of ferroelectric stripe domains (FE) into a
continuous magnetic thin film (lower images). In this case,
one-to-one copies of the ferroelectric domain pattern is
obtained by efficient strain coupling
