Complex dynamics of ferromagnetic ferrofluid

Suspenzijo feromagnetnih delcev imenujemo feromagnetni ferofluid, če tvori feromagnetno fazo. V tem delu so predstavljeni rezultati, opažanja in meritve, ki sem jih izvajal na feromagnetni suspenziji nanoploščic dispergiranih v terc-butanolu. To vključuje meritve magnetne histereze s pomočjo magnetometra z vibrirajočim vzorcem, meritve difuzijskih konstant z dinamičnim sipanjem svetlobe ter meritve dinamike progaste strukture, ki se pojavi v izmeničnem magnetnem poljuA suspension of ferromagnetic particles which forms a ferromagnetic phase is called a ferromagnetic ferrofluid. In this work the results, observations and measurements that I conducted on a ferromagnetic suspension of nanoplatelets dispersed in terc-butanol are presented. This includes measurements of magnetic hysteresis with the help of a vibrating sample magnetometer, measurements of diffusion constants by dynamic light scattering and measurements of dynamics of a striped structure which appears in the presence of an alternating external magnetic field
