Метод оценки ширины доменной стен­ки по сигналу, генерируемому доменной стенкой при прохождении через измерительную катушку

Страницы / Pages


Выведена формула для ЭДС индукции Фарадея от движущейся в микропроводе доменной стенки. Производная по времени магнитного потока в измерительной катушке выражается через пятикратный интеграл по объему стенки и поверхности сечения катушки. Полу­чен­ное выражение сравнивается с полученными ранее при упрощенном опи­сании объектов измерения.


The formula for the emf Faraday induction from a domain wall moving in a microwire is derived. The time derivative of the magnetic flux in the measuring coil is expressed through a five-fold integral over the wall volume and over the coil section surface. The resulting expression is compared with those obtained previously with a simplified description of the measurement objects.
