Аннотация

Материал Mn(Bi,Sb)2Te4 известен как собственный магнитный топологический изолятор, в котором точка Дирака может быть локализована на уровне Ферми путем замещения атомов Bi атомами Sb. Это необходимо для реализации квантового аномального эффекта Холла и других уникальных квантовых эффектов. Ранее в литературе было показано, что для образцов Mn(Bi1-x Sbx)2Te4 характерно антиферромагнитное упорядочение в широких пределах изменения x (от 0 до 0.5). В данной работе экспериментально показан смешанный тип магнитного упорядочения, подразумевающий наличие одновременноферромагнитного и антиферромагнитого порядков в системе. Установлены основные воспроизводимые магнитные характеристики данной магнитной структуры и их поведение в зависимости от изменения концентрации атомов Sb.

N2 - It is known that Mn(Bi1 –xSbx)2Te4 is an intrinsic magnetic topological insulator, where the Dirac point can be localized at the Fermi level by substituting Bi atoms for Sb atoms to implement the quantum anomalous Hall effect and other unique quantum effects. It has already been shown that Mn(Bi1 – xSbx)2Te4 samples has antiferromagnetic order in a wide range of Sb concentration x = [0, 0.5]. In this paper a mixed type of magnetic ordering is experimentally demonstrated. This implies that there is both a ferromagnetic and an antiferromagnetic order in the system. We revealed the main reproducible magnetic characteristics of this magnetic structure, as well as their dependence on the concentration of Sb atoms.
