Two-dimensional (2D) magnetic materials with magnetic anisotropy can form magnetic order at finitetemperature and monolayer limit. Their macroscopic magnetism is closely related to the number of layers andstacking forms, and their magnetic exchange coupling can be regulated by a variety of external fields. Thesenovel properties endow 2D magnetic materials with rich physical connotation and potential application value,thus having attracted extensive attention. In this paper, the recent advances in the experiments and theoreticalcalculations of 2D magnets are reviewed. Firstly, the common magnetic exchange mechanisms in several 2Dmagnetic materials are introduced. Then, the geometric and electronic structures of some 2D magnets and theirmagnetic coupling mechanisms are introduced in detail according to their components. Furthermore, we discusshow to regulate the electronic structure and magnetism of 2D magnets by external (field modulation andinterfacial effect) and internal (stacking and defect) methods. Then we discuss the potential applications ofthese materials in spintronics devices and magnetic storage. Finally, the encountered difficulties and challengesof 2D magnetic materials and the possible research directions in the future are summarized and prospected. DOI: 10.7498/aps.71.20220301

Abstract

Two-dimensional (2D) magnetic materials have attracted significant attention for promising applications in energy-saving logic and robust memory devices. However, most 2D magnets discovered so far typically feature drawbacks for practical applications due to low critical temperatures. Herein, we synthesize ultrathin room-temperature (RT) magnetic Fe7Se8 nanoflakes via the space-confined chemical vapor deposition method. It is found that the appropriate supply and control of Se concentration in the reaction chamber is crucial for synthesizing high-quality nonstoichiometric Fe7Se8 nanoflakes. Cryogenic electrical and magnetic characterizations reveal the emergence of spin reorientation at ∼130 K and the survival of long-range magnetic ordering up to room temperature. The RT magnetic domain structures with different thicknesses are also uncovered by magnetic force microscopy. Moreover, theoretical calculations confirm the spin configuration and metallic band structure. The outstanding characteristics exhibited by Fe7Se8 nanoflakes, including RT magnetism, spin reorientation property, and good electrical conductivity, make them a potential candidate for RT spintronics.
