Magnētiska piliena līdzsvara figūru skaitlisks aprēķins augstfrekvences rotējošā magnētiskā laukā

2016

Darbā tiek apskatīts, kā atrast magnētiska piliena līdzsvara ﬁgūras gan konstantā magnētiskā laukā, gan augstfrekvences rotējošā magnētiskā laukā izmantojot enerģijas minimizēšanu. Izmantojot demagnetizācijas koeficientu sakarības trīsasu elipsoīdam tiek iegūta izteiksme piliena enerģijai magnētiskā laukā. Līdzsvara figūru atkarība no magnētiskā lauka un magnētiskā piliena parametriem (magnētiskais Bonda skaitlis, piliena magnētiskā uzņēmība) tiek aprēķināta veicot enerģijas minimizāciju. Apskatīta magnētiska piliena līdzsvara figūru stabilitāte augstfrekvences rotējošā magnētiskā laukā. Tiek salīdzināti iegūtie rezultāti ar citiem darbiem (eksperimentiem un skaitliskām simulācijām).
