In present work the results about study of spectral features of the magneto-optical hysteresis loop (Faraday rotation) vertical shifting effect in the magneto-plasmonic nanocomposite Bi:YIG/Au( NP )/GGG are shown. It is shown that in the spectral range near localized plasmon-polariton resonance (LPPR) the magneto-optical hysteresis loop has a vertical shift (Faraday “delta”). The loop shifting at the left and right side of the LPPR have a different sign and in the resonance the loop shifting become null. It is shown that the spectral locations of Faraday “delta” maxima are due to the width of the LPPR resonant line.
