Positioning of magnetic particles in polymer matrices for smart material engineering by magnetically patterned exchange bias templates — •Iris Koch1, Markus Langner2, Andreas Greiner2, and Arno Ehresmann1 — 1Department of Physics and Center for Interdisciplinary Nanostructure Science and Technology (CINSaT), University of Kassel, Heinrich-Plett-Str. 40, D-34132 Kassel — 2Department of Macromolecular Chemistry II, University of Bayreuth, Universitätsstr. 30, D-95440 Bayreuth
Magnetic micro-stripe patterned exchange bias systems with different stripe widths were used as a template for the precise positioning of either pure ferromagnetic nanoparticles or superparamagnetic core-shell microspheres in polymer thin film systems. The positioning was assisted by an out-of-plane magnetic field superimposing the magnetic field landscape of the exchange bias substrate. The particle/polymer composite was subsequently obtained via lift-off from the magnetically patterned template. An interaction with external magnetic fields was observed in air and in liquid environment down to a mass fraction of 3 % magnetic material in relation to the polymeric material.
