Penentuan Nilai Koefisien Linear Magneto Optik Bahan Transparan Menggunakan Interferometer Michelson

Abstract

The research refractive index change in a transparent materials caused by magnetic field have done by using Michelson interferometer test. To know the change of refractive index that happened done by change calculated from fringe. By using laser He- Ne laser by l = 632,8 nm and output power 1 mW. The research is doing by variation field magnated and concentration. By magnate field and concentration will getting refractive index change. And from refractive index change will getting value from optical magneto coefficient linear by using Michelson interferometer. The result was getting that before magnetic field influence, existence of transparent materials caused density of fringe increased. It was showing change of refractive index. And from refractive index change will getting value from optical magneto coefficient linear that improve because of concentration, and value from optical magneto coefficient linear on orde10 -12 .
