ANALYSIS OF MAGNETO OPTICAL PROPERTIES IN NOVEL MAGNETIC SUPERLATTICE SYSTEM

Abstract

The variation of refractive index with frequency of Silver doped magnetic material (YIG) of bulk nanocomposite system is studied. Hence, the polariton dispersion of a novel magnetic superlattice system consisting alternating layers of YIG based metal nanocomposite system and YAG is studied. The polaritonic gap is analysed for various filling factor for both the bulk and superlattice system. It is found that the width of the polaritonic gap is reduced in the case of superlattice system when compared to the bulk system.
