Abstract
A data storage device comprising a recording head having a high damping magnetic alloy layer including 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.
