Обнаружено два режима проводимости в «зигзаговых»конфигурациях Pt -Feнанопроводов: «высокопроводящее состояние» и «низкопроводящее состояние». Для137«высокопроводящего состояния» величина проводимости через спин-вверх канал порядка 2G0, а через спин-вниз канал 1 G0. Для «низкопроводящего состояния» транспорт есть толькочерез спин-вверх канал на уровне Ферми (~ 1 G0), транспорт через спин-вниз канал равеннулю. («низкопроводящее состояние» является основным состоянием для «зигзаговой»конфигурации Pt -Fe нанопроводов).9. Расчеты проводимости показали, что «низкопроводящее состояние» Au-Co и PtFe нанопроводов представляет собой спин-фильтр систему.138СПИСОК ЛИТЕРАТУРЫ:[1] Tatsuya Konishi, Manabu Kiguchi, Kei Murakoshi, «Electric Conductance of Rh AtomicContacts under Electrochemical Potential Control», Phys.
