И бретение относитс к области элекг/joHHoro пара лагнитного резонанса (ЭПР) и может быть использовано при конструировании спектрометров ЭПР.And shaving is in the field of electric / joHHoro pair of impedance resonance (EPR) and can be used in the design of EPR spectrometers.
Известны способы исследовани насыщени линии ЭПР, в которых магнитное поле модулирует так, что амплитуда модул ции больше ширины линии, а врем прохождени через линию много меньше времени сцин-решеточной релаксации , причем синхронно с частотой модул ции осуществл етс импульсное насьщение небольшого участка линии ЭПР l.There are known methods for studying the saturation of an EPR line, in which the magnetic field modulates so that the modulation amplitude is greater than the line width, and the transit time through the line is much shorter than the time of scin-lattice relaxation, and a small portion of the EPR line is pulsed synchronously with the modulation frequency. .
Однако эти способы не позвол ют исследовать поведение линии во врем действи насыщающих высокочастотных импульсов из-за возникающих при этом паразитных сигналов.However, these methods do not allow to investigate the behavior of the line during the action of saturating high-frequency pulses due to the parasitic signals arising in the process.
Известен также способ исследовани насыщени лшши ЭПР, заключающийс в воздействии на сшгаовую систему непрерывным насыщающим высокочастотным полем, прохождении через резонанс медленно измен ющимс по сравнению со скоростью спин-решеточной релаксации пол ризующим магнитным полем, модулированным по синусоидальному закону, и .узкрполосной регистрации линии ЭПР, причем амплитуда модул ции меньше ширины изучаемой шпши (метод последовательного насьш1ени ) 2.There is also known a method for studying the saturation of an EPR line, which involves exposing the shear system to a continuous saturating high-frequency field, passing through a resonance by a polarizing magnetic field modulated by a sinusoidal variable with a slow-wave, compared to the spin-lattice relaxation rate, moreover, the modulation amplitude is less than the width of the studied shspy (the method of sequential homing) 2.
Недостатком этого способа вл етс то, что он не обеспеч1шает.регистрации временных характеристик процесса насыщени из-за усреднени во времени неравновесной намагничетюсти непрерьтными . высокочастотным и модул ционным пол ми.The disadvantage of this method is that it does not ensure that the registration of the temporal characteristics of the saturation process due to the time averaging of non-equilibrium magnetizing is unfeasible. high frequency and modulation fields.
Цель изобретени - получение временных характеристик процесса насыщени линии ЭПР.The purpose of the invention is to obtain temporal characteristics of the process of saturation of the EPR line.
