摘　　要：The synchronization of nonlinear systems has been demonstrated in several natural systems,which not only enhances the performance of spin torque oscillators(STOs)but also enables the modification of STOs for new computing architectures.This paper reviews recent advances in the mutual synchronization,forced synchronization,and noise synchronization of STOs from both theoretical and experimental perspectives.The main types of synchronization discussed include spin wave synchronization,dipolar field synchronization,electrical connection synchronization,and injection locking.After introducing the theoretical and experimental progress in these fields,we highlight the importance of synchronization for practical applications in both microwave devices and neuromorphic computing.The significance of these studies for understanding and applying STO synchronization is emphasized,and we offer our perspective on current research,suggesting directions for future studies.
