| titleOfInvention | Cobalt-platinum-ruthenium-based sputtering target, preparation method thereof and magnetic recording layer |
| abstract | The present invention provides a cobalt platinum rhodium sputtering target, a preparation method thereof and a magnetic recording layer. The cobalt platinum ruthenium sputter target and the magnetic recording layer have a similar composition, comprising cobalt, platinum and rhodium, the ruthenium content being greater than or equal to 0.2 atomic percent and less than or equal to 3.5 atomic percent, and the platinum content relative to cobalt and The ratio of the content of platinum is greater than or equal to 0.15 and less than or equal to 0.3. By controlling the composition of the cobalt-platinum-ruthenium-based sputtering target and the magnetic recording layer, it is possible to improve the saturation magnetization amount, the magnetocrystalline anisotropy constant, and the grain size uniformity of the magnetic recording layer, thereby making the magnetic recording layer-containing layer The magnetic recording medium has a high magnetic recording density and a good recording quality. |
