AbstractWe demonstrate that the forced transient dynamics of a nonlinear (nonisochronous) auto-oscillator is qualitatively different from the dynamics of a quasilinear oscillator described by the classical Adler's model. If the normalized amplitude μ of the driving force exceeds a certain critical value μ cr, the transition to the synchronized regime becomes oscillatory with a frequency proportional to ∝√ μ- μ cr and a synchronization time that is almost independent of μ. The discovered effect is illustrated on the example of a strongly nonlinear spin torque nano-oscillator (STNO) where the finite transient synchronization time can limit the possible range of STNO modulation frequencies. © 2010 The American Physical Society.
