Abstract
Spin splitting plays a pivotal role in most modern spintronic effects. Conventionally, spin splitting accompanied by macroscopic magnetic moments has been typically discussed in the context of ferromagnets. Nevertheless, the amalgamation of spin splitting and antiferromagnets has led to a range of intriguing magnetoelectronic effects in the field of antiferromagnetic spintronics. Considering this perspective, this Letter focuses on exploring the emerging area of spin-split antiferromagnetic spintronics. It begins with a brief overview of the historical development of the anomalous Hall effect. Subsequently, recent studies on the spin-splitting-related anomalous Hall effects in antiferromagnets are elaborated upon. Finally, a summary is provided outlining the occurrence of spin splitting in different types of antiferromagnets, including noncollinear antiferromagnets and collinear altermagnets. Additionally, the associated magnetoelectronic effects are discussed.
