The non-reciprocity of magneto-optical reflection response by surface plasmon excitation in the planar Au/Fe/Au/glass and Au/Fe/glass systems with prism coupling is studied. These structures are intended as the sensor units combining magneto-optical and suface-plasmon-resonance effects. To simulate the response of discussed structures to external magnetic field theoretical model based on matrix algorithm is applied. The ability of MO-SPR systems to sensing of magnetic field is verified using proposed repsonse factors r ± (f) and F. Obtainded theoretical results experessed by introduced sensitivity criteria are confirmed by experiments realized by Multiscope device.
