| 英文摘要 | Nanotwinned materials have recently attracted intense interest since they often exhibit excellent mechanical properties that are far superior to those of the corresponding single crystals. However, how nanotwinned structures affect the physical properties of functional materials remains almost unexplored. In this study, we demonstrate ferrimagnetism in a nanotwinned antiferromagnetic Cr2O3 thin film. The Cr2O3 thin film grown on the SrTiO3 substrate comprises high-density nanotwins and exhibits an obvious room-temperature ferrimagnetic property, though the bulk Cr2O3 is intrinsically antiferromagnetic. Aberration-corrected transmission electron microscopy investigations reveal that the twin boundaries (TBs) of Cr2O3 are stoichiometric and have two types of atomic structures (i.e., denoted by type I and type II). First-principles calculations suggest that the type I TB exhibits an antiferromagnetic nature without a net magnetic moment, while the type II TB is ferrimagnetic and has a net magnetic moment of 3.0 mu(B)/f.u. These findings suggest that nanotwins in functional materials can generate physical properties distinct from those of single crystals, thereby providing an efficient strategy for material design and performance control. |
