Аннотация
Для исследования разбавленных магнитных наножидкостей применялась чувствительная лазерная регистрация слабых поляризационно-оптических откликов. Рассмотрены критерии слабого и сильного сигналов при зондировании образца лазерным излучением с глубокой модуляцией поляризации. Исследованы магнитооптические отклики жидкости на основе керосина с наночастицами магнетита в широком (пять порядков) диапазоне концентраций. Слабые поляризационные отклики для этой наножидкости наблюдались при рекордно низких объемных концентрациях наночастиц до 10-7.
