(a) Arnold tongue computed for mT and A/cm2 varying the magnitude of RF current and field. (b) Phase difference between external force (current or field) and output magnetization as a function of dc current when an RF source at the same frequency of the free precessional one is applied.Filled-red circle: RF current, white circle: RF field.
