文摘
- •
Highly textured NdFeAs(O,F) thin films were obtained by a direct growth method.
- •
Enhancing the migration was crucial to realize the direct growth.
- •
The critical current density exceeded 3 MA/cm2 at self-field and 1 MA/cm2 at 9 T.
- •
A two-dimensional growth was confirmed by the observation of surface morphology.
