Исследованы термодинамические, магнитные и фрустрационные свойства обобщенной модели Изинга на квадратной решетке с двумя трансляциями в горизонтальном и вертикальном направлениях. Установлены новые особенности, возникающие в обобщенной модели Изинга.</p></trans-abstract></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>E.
