摘要：

The influence of temperature on the magnetic-field-driven domain wall motion is investigated in GdFeCo ferrimagnets with perpendicular magnetic anisotropy (PMA). We find that the depinning field strongly depends on temperature. Moreover, it is also found that the saturation magnetization exhibits a similar dependence on temperature to that of the depinning field. From the creep-scaling criticality, a simple relation between the depinning field and the properties of PMA is clearly identified theoretically as well as experimentally. Our findings open a way for a better understanding of how the magnetic properties influence the depinning field in the magnetic system and would be valuably extended to depinning studies in other systems.
