Paramagnētisku daļiņu ķēdes rotējošā laukā

2020

Šajā darbā ir veikti paramagnētisku daļiņu kustības skaitliskie aprēķini viskozā šķidrumā rotējošā laukā. Modelī tiek izmantotas daļiņas ar vienas ass magnētisko anizotropiju. Pēc veikto simulāciju rezultātiem tika izpētīti daļiņu rotācijas režīmi ķēdēs, kad daļiņas anizotropijas ass spēj un kad nespēj izsekot lauka rotācijai un parādīta šo režīmu ietekme uz ķēdes stabilitāti rotējošā laukā. Ir iegūta maksimālā, jeb kritiskā lauka rotācijas frekvence pie kādas ķēde nesalūst, atkarībā no ķēžu garuma pie dažādiem magnētiskās anizotropijas parametriem. Skaitliskie rezultāti salīdzināti ar literatūrā atrodamiem teorētiskiem rezultātiem. Ja daļiņas telpā izkārto haotiski, tad pēc iedarbošanās ar…
