CoNiCr/Cr sputtered thin film disks
TL;DR: A new CoNiCr/Cr film for the thin film hard disk has been developed by adding Ni and Cr to a Co thin film, a high coercive force was obtained and the high resistance against humidity test could be obtained as discussed by the authors.

Film structure and magnetic properties of CoNiCr/Cr sputtered thin film
TL;DR: In this article, the authors studied the origin of the high coercive force of sputtered CoNiCr/Cr film and showed that the CoNiC/Cr has a fine grain structure with magneto-crystalline anisotropy oriented in the plane, which results in a high coercive forces in the film plane.

A comparison of the magnetic and recording properties of sputtered ternary alloys for high density applications
TL;DR: In this paper, the authors evaluated the coercive force of CoCrTa, CoNiCr, CoCrW and CoNiW alloys relative to magnetic characteristics and recording performance and found that these alloys exhibit high squareness (Mr/Ms) and high coercive force suitable for high-performance magnetic recording applications.
