Paper Abstract

Light diffracted on magnetic domain structure changeable by external magnetic field can be used for fiber - optic switches. Quantitative and comfortable received information about the changeable diffracted light distribution as a function of both polar and azimuthal angles σ, γ is important for this device. Two fully automated spatial filter stations S1 and S2 were constructed for σ and γ angle light distribution analysis, respectively. The S2 station gives new opportunities for analysis of domain structures preference induced e.g. by external magnetic fields. Samples with different σ quality parameter from (Y,Sm,Bi)3 (Ge,FE)5 O12 series grown on (111) GGG substrates were investigated. The obtained results were discussed in comparison with results earlier published.
