Microwave assisted magnetization reversal (MAMR) is a new scheme to achieve high-density magnetic recording. Spin torque oscillator (STO) is expected to be an attractive cadidate as a microwave source for MAMR. In this work, we perform numerical simulations of magnetization dynamics in an STO with two free layer, and find severnal dyanmical phases such as synchronization and chaos.
