20.500.12556/RUL-168868 Magneto-optični odziv feromagnetnega ferofluida v tanki kapilari Magneto-optical response of ferromagnetic ferrofluid in thin capillaries Feromagnetni ferofluid je poseben tip tekočine, ki ohranja feromagnetne lastnosti tudi v odsotnosti magnetnega polja. V sklopu magistrske naloge sem preučeval odziv suspenzije feromagnetnega ferofluida na motnjo povzročeno z magnetnim poljem. Spreminjanje napetosti na tuljavi je povzročalo spremembe v urejenosti feromagnetnih ploščic v suspenziji. Spremembe urejenosti je mogoče preučevati z optičnim polarizacijskim mikroskopom, ker so suspenzije v nematski fazi dvolomne. Eksperimenti so bili izvedeni v prisotnosti zemeljskega polja in ob izničenju zemeljskega magnetnega polja. Ferromagnetic ferrofluid is a special type of liquid that retains ferromagnetic properties even in the absence of magnetic field. As part of this master's thesis, I investigated the response of a suspension of ferromagnetic ferrofluid to a disturbance caused by magnetic field. Changing the voltage on the coil caused the changes in arrangement of the ferromagnetic particles in the suspension. Because the suspensions in the nematic phase are birefringent, it was possible to study the the changes in magnetic ordering by polarized optical microscope. Experiments were first conducted in the presence of the Earth's field and in zero field condition in which the Earth's magnetic field was compensated. feromagnetni ferofluidi dvolomnost izotropna faza nematska faza ferromagnetic ferrofluids birefringence isotropic phase nematic phase true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-05-02 08:15:17 2025-05-02 08:15:22 2025-05-06 08:07:52 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 150186 232845059 16752.pdf 16752.pdf 1 FC239CC0980F252D5A8B661DE0733F09 c94e74d3bc66084e9d7ebce108e83bf9517878db7c103c9e31ada5457a706eca af403c39-271b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=209938 Fakulteta za matematiko in fiziko 0 0 0
