Claim 0:
1. A data storage device comprising:
a recording head having a high damping magnetic alloy layer comprising:
at least one magnetic alloy element; and
a 5d transition element;
the high damping magnetic alloy layer having a mixed face-centered cubic (fcc) and body-centered cubic (bcc) crystal structure; and
the mixed fcc and bcc crystal structure comprising fcc and bcc grains, with the bcc grains having an elongated shape relative to the fcc grains, a larger size than the fcc grains, and slip deformation, thereby providing the high damping magnetic alloy layer with a damping constant of up to about 0.07.
