摘要：

We study the time dependent magnetic behavior of uniaxial cobalt films in the vicinity of the dynamic phase transition (DPT) as a function of the period P and bias H-b of an oscillating magnetic field. In addition to the DPT at a critical period P-c, we observe the occurrence of transient behavior for P < P-c. Our data can be consistently explained by the existence of a phase line at H-b = 0 for P < P-c, which causes a first order phase transition in between two antiparallel dynamic order states, thus indicating far-reaching similarities of the DPT to equilibrium phase transitions in ferromagnets.
