The sweep rate dependence of the electrical control of magnetic coercivity" (2012). Stephen Ducharme Publications. 84. The sweep rate dependence of the coercive field in magnetic thin films is well-known. Here we present an experimental investigation of the dependence of electric field control of magnetization on the magnetic field sweep rate. Our sample is a ferroelectric/ferromagnetic heteros...

In this paper the authors have grown germanium telluride thin films by molecular beam epitaxy on silicon as a proposed system for ferroelectric-based spintronics with high spin-orbit coupling. The structure of ferroelectric domains is explored in wide range film thickness. After elucidating domain wall type and volume fraction, stability respect to thermomechanical stress discussed.

Using the model system of ferroelectric domain walls, we explore the effects of long-range dipolar interactions and periodic ordering on the behavior of pinned elastic interfaces. In piezoresponse force microscopy studies of the characteristic roughening of intrinsic 71° stripe domains in BiFeO3 thin films, we find unexpectedly high values of the roughness exponent ζ=0.74±0.10, significantly di...

Using calculations from first principles and the concept of layer polarization, we have elucidated the nanoscale organization and local polarization in ferroelectric thin films between metallic contacts. The profile of the local polarization for different film thicknesses unveils a peculiar spatial pattern of atomic layers with uncompensated dipoles in what was originally thought to be a ferroe...
