<p>Provided are a CrTi-based alloy for adhesion film layers for use in magnetic recording media, a target material for sputtering, and a perpendicular magnetic recording medium obtained using the alloy. This alloy is a CrTi-based alloy in which the empirical formula in terms of atomic ratio is represented by (Cr,Mo,W)X(Ti,Ta,Zr)100-X, where 40<=X<=70, in which the Cr element has been replaced with one or the two elements selected from between Mo and W in such an amount that the proportion of Mo+W is in the range of 10 at% to X/2 at%, and in which the Ti element has been replaced with one or the two elements selected from between Ta and Zr in such an amount that (Ta+Zr)<=20 at% (including 0 at%).</p> |
