“…2 shows the experimental specific surface area on TEOS content in the initial sol dependence. As noted in [32], the highest efficiency of spin-spin relaxation of the protons magnetization can be achieved by using colloidal nanoparticles derived from sol with 60 vol.% TEOS which correlates with the maximum of the specific surface area about 60…70 vol.% TEOS content. So specimens based on initial sol with 60…70 vol.% TEOS were used for further investigations.…”

“…Взаимодействие коллоидных частиц на основе оксида железа с внешним магнитным полем может приводить к формированию агрегатов, ориентированных вдоль си-ловых линий магнитного поля [17]. Полученные ранее экспериментальные результаты показали, что компо-зитные частицы Fe m O n −SiO 2 способны коагулировать под действием постоянного магнитного поля, при этом водные коллоидные растворы частиц теряют седимента-ционную устойчивость [16].…”
