Notes:
We have investigated Co1−xCrx/Pt multilayers as potential perpendicular media capable of high-density magnetic recording. The films exhibited strong perpendicular anisotropy, coercivity values ranging from 0.3 to 6.9 kOe, and a range of coercive squareness (S*) from 0.21 to 0.96. Magnetic and atomic force microscopy were used to correlate the grain and magnetic domain structures. The degree of intergranular exchange is clearly dependent on the deposition temperature and, to a lesser extent, Cr content. Co1−xCrx/Pt multilayers are ferromagnetic at room temperature for x〉30%, which is not observed in thick Co1−xCrx films. Initial recording results determined a SONR ratio of 23 dB for a [Co(4 Å)/Pt(5 Å)]10 multilayer recorded at 10 kiloflux changes per millimeter using a standard longitudinal ring head. © 2000 American Institute of Physics.
