Document Type and Number:
WIPO Patent Application WO/2020/040082
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a Co-based alloy with which it is possible to produce a target exhibiting excellent toughness and to obtain a soft magnetic layer having a low saturation magnetic flux density. With a view to solving said problem, the present invention provides a Co-based alloy for use in a soft magnetic layer of a magnetic recording medium, said alloy comprising 11-25 at% of one or more types of element XA selected from the group consisting of Nb, Mo, Ta, and W, 0.4-10 at% of one or more types of element XB selected from the group consisting of V, Cr, Mn, Ni, Cu, and Zn, with the remainder being Co, Fe, and unavoidable impurities, wherein the total content of the element XA and the element XB is less than 30 at%.
