FIG. 4.

Comparison of magnetization curves recorded at the indicated temperature for GdCoFeB (a) and magnetic phase diagram of GdCoFeB as determined from the evolution of the critical field μH obtained in the magnetization curves. The full symbols are derived from steady field and the empty symbols from high pulsed magnetic field (b).
