Abstract

We have investigated as series of substituted NdFeB thin films (NdFeBX where X = Co, Cu, Ti. Zr partially replacing Fe) of different thickness. The perpendicular coercivity has a maximum of 2700 Oe for a thickness of 200 nm after annealing at 625 °C for 15 mins. It is found that coercivity can be controlled by varying the thickness of the films. We have observed that the grain size is controlled to less than 25 nm in the substituted films.
