The objective of this paper is to investigate the magnetic nature of Dilute Magnetic Dielectrics (DMD) under variation of external magnetic field. The said variation is studied over developed nano sized Gadolinium Nickel Sulfide complex, Cobalt Sulfide, Nickel Sulfide and Titanium Sulfide as a DMD system. The observed experimental field variation of the effective magnetic permeability is the analyzed results of optical experiment. The experiment records the variation of Brewster angle of incident polarized LASER beam from the surface of developed DMD specimen with applied out of plane external magnetic field. The relative permittivity and relative magnetic permeability were estimated by following the electromagnetic theory. The overall results obtained are found to be holding a good agreement between theory and experiment.
