Magnetization fluctuations and characteristic lengths for sputtered CoP/Cr thin-film media
Magnetization fluctuations of uniformly magnetized media have been measured in sputtered CoP thin films as a function of Cr underlayer thickness. Increasing underlayer thickness from 20 to 400 nm in n...

The nature of media recording noise in metallic, quasiparticulate thin films is principally related to the grain size, crystallographic orientation, and intergranular exchange and magnetostatic coupling in the films. In this study the results of a magnetic evaluation of magnetostatic interactions in CoNiCr thin films of varying Cr underlayer thickness are reported. The evaluation is undertaken through the measurement and comparison of remanence curves. The results presented here indicate enhanced cooperative switching as Cr underlayer thickness is reduced from 2000 to 100 Å, with a strong correlation between signal-to-noise measurements. In addition, the transition from principally exchange-coupled to quasiparticulate thin films, as Cr underlayer thickness increases, has been established.<lz> <lz> <lz> <lz> <lz> <lz>
