Оглянуто коливні властивості (як класичні, так і квантові) Блохової цятки (БЦ) у доменній стінці циліндричного феромагнетного нанодроту. На основі одержаних результатів зроблено висновок щодо можливости розгляду БЦ у якості гармонічного осцилятору. Воднораз квантові коливання БЦ являють собою різновид магнетного макроскопічного квантового ефекту [1], який у випадку ніклевого та залізного нанодротів відбувається в області гелійових температур. Показано перетворення хвильового пакету БЦ у процес биття, що забезпечує трансфер енергії квантового осцилятора. Наведені результати мають особливий інтерес у контексті розвитку сучасних нанотехнологій, заснованих на фізичних властивостях циліндричних феромагнетних нанодротів, магнетна структура яких характеризується наявністю доменних стінок із БЦ.

Ключові слова: циліндричний феромагнетний нанодріт, доменна стінка, Блохова цятка, гармонічні осциляції, хвильовий пакет, биття.
