Spatially resolved magneto-optic surface plasmon resonance measurements in IrMn/Co/Au layers with parallel-stripe domains — •Nicolas Müglich, Sebastian Kübler, Kerstin Kämpf, Friedrich Herberg, and Arno Ehresmann — Department of Physics and Center for Interdisciplinary Nanostructure Science and Technology (CINSaT), University of Kassel, Heinrich-Plett-Str. 40, D-34132 Kassel

In the past it has been demonstrated that the sensitivity of surface plasmon resonance (SPR) based biosensors can be improved by a combined measurement of the SPR effect and the transverse magneto-optic Kerr effect. The magneto-optic surface plasmon resonance (MOSPR) of Au/IrMn/Co/Au exchange biased thin film systems, magnetically stripe patterned by He ion bombardment, has been measured spatially and angular resolved in transverse geometry. We show promising results which indicate that MOSPR based sensors may be designed without the usage of external magnetic fields in the future.
