| Outline of Final Research Achievements |
The present study was done to develop the measurement system of magnetic optical rotation using optical fiber. The following results were obtained:1)A new instrument to measure the magnetic optical rotation of liquid and solid samples with high sensitivity was constructed by the application of the principle of Sagnac interference effect. 2)The magnetic birefringence of magnetic nanoparticles in liquids was measured by the measurement of the Sagnac effectdue to the application of magnetic field. 3)By the use of the magnetic Sagnac instrument, it was found that the magnetic linear dichroism of the sample could be measured and it could be applied to the magnetic nanoparticles. 4) By using a 850 nm laser, polarizatin maintaining optical fibers and a fiber polarizer, the instrument to measure the magnetic Sagnac effect was constructed.
