These results were obtained using the MicroMagus software package, ver. 5.15. The discretization used was 200 x 50 x 1 (i.e., cell size 2.5 nm x 2.5 nm x 3 nm). The time integration method was an optimized Bulirsch-Stoer with adaptive step size control; integration accuracy is 10^-6.

Results:

• Field applied at 170° from the x-axis (Field 1):
  

  Time evolution of spatially averaged magnetization components for field 1.
  
  

  The magnetization distribution corresponding to the first time <M_x> = 0 for field 1.
  
  
  

• Field applied at 190° from the x-axis (Field 2):
  

  Time evolution of spatially averaged magnetization components for field 2.
  
  

  The magnetization distribution corresponding to the first time <M_x> = 0 for field 2.
  
  
  

Data:

• Field 1: Time series, and Vector data at <M_x> = 0.
• Field 2: Time series, and Vector data at <M_x> = 0.
