Abstract :
Compositionally and morphologically modulated TbCo films were prepared on glass substrates by changing negative bias voltage between 0 and 100V or 150V alternately using RF sputtering method. The films having 12 - 36 layers (layer thickness of 250 - 80 Å) show high magnetic coercivity and high resistivity to oxidation. In these films, small stable bits can be written magneto-optically.
