Properties of NdFeB film grown on silicon substrate by PLD under external magnetic field

Nd-Fe-B films were grown on silicon substrate subjected to perpendicular magnetic field using pulsed laser deposition. The effect of substrate temperature (250-650 °C) on the magnetic properties of the film was studied. Magnetic anisotropy was observed in amorphous deposited film. Minor Nd2Fe14B crystalline phase was found when films were deposited at 500 °C and 650 °C. No obvious magnetic crystalline anisotropy shown after the correction of shape anisotropy.
